Title: Laser printers without smart chips in the toner cartridges?
Post by: dor123 on April 23, 2017, 08:21:08 AM
Is there any manufacturer of laser printers that still produces laser printers that uses optical mechanisms to accurately measure the amount of remained toner in the cartridge, and that don't have these smart chips that lies about the remained toner and declares the cartridge empty while it is actually full?

Color or black or white laser printer ?

Most "smart chips" aren't that smart and can be easily bypassed allowing you to refill the toner, the only major issue people have when they do this is they don't empty the toner waste compartment and it starts to leak and makes a mess on the printing, most aren't hard to empty but it does involve splitting the toner cartridge apart, normally a few screws or plastic clips, some are even glued, but if they also contain the drum make sure you do it in a dimly lit room, the drum is photosensitive and can be damaged if exposed to bright lighting or sunlight for extended periods and wear lint free clean gloves, getting those finger prints off the drum really sucks to do later and handle it carefully any dents, dings or scratches will pick up toner and print it on every page, every time, and most drums do several revolutions per page printed so it will be all over the paper...

What model are you looking at getting or can be gotten cheaply around you ?  Maybe we can tell you how to fix it ...

I asked this. My hostel HP D1360 inkjet printer, stopped working, jamming paper during feeding from the feed tray and the print head can't be moved, so they have to replace the printer. Laser printer is the perfect choice for my hostel, since they prints a lot of documents, and they don't so needs color, so a B&W laser printer would be good for them.
As far as I know: HP are crappiest printers in terms of planned obsolescence, with HP known to use expiration dates and to count the amount of the pages printer to declare the cartrige empty and refuse to print, while it is still have 60% of the toner remained, and they also refuses to work with a 3rd party cartridge. Samsung printers are designed to stop working after sometimes, displaying a message to replace the imaging drum, despite it is still usable. Brother uses a sensor that try to lie in measuring the amount of remained toner in the cartridge. Lexmark don't supports 3rd party cartridges. I don't know what about Epson, Canon, Xerox and OKI, in the field of laser printers.

Ok most Samsungs you can reflash the firmware so they don't care what you do, toner, fuser, drum, you actually have to tape over the smart chip contacts, and the cheaper ones you can actually print until they are empty, it just warns you and beeps every now and then...

HP, well the newer stuff is mostly junk but the older stuff like a 4L is built like a tank and weight about 100lb I've seen them do a million pages before needing new rollers and you can simply pour in the toner when the pages get light and they cheap like $5 USD for 10,000 pages, but they only do like 4 Pages/min but if you need a 1000 page manual you do it before going to bed and it will be done when you wake up..

The brothers they lie, the cheaper ones use a mechanical flag and gears to say it's empty, they do sell different gears so they lie to the printer, but for the most part they will just keep printing until it's actually empty, you just get prompted every time you print, I just print to default windows printer not using brothers software to avoid this and you can reset the other stuff to new in the menu, but it sucks if your using the network to print but straight USB or real old school LPT it's not an issue, and you can reset the other stuff like drums in the menu..

Lexmark, well the commercial ones I refill them all the time, they don't seem to care, and will print until they are empty and most get junked because they start having feed problems, but most of the rollers you can slide them off turn them inside out and stuff them back on and get another half a million pages through it, or hit them with real fine sand paper to remove the glazing, they are well worth saving if you find them for free, and some times you need to replace the fuser wiper, and clean the corona wire, but you need to do this to most printers,and if they are free look for the additional paper holders, they normally throw them out with the printer and you might score a 5000 page feeder or three of them so you don't need a table to stick it on...

And if your really stuck you can get replacement smart chips for just about any toner cartridge online for a few bucks a piece, or at the same place you buy the toner from and they will look like a new cartridge to the printer...

My experience with BW laser printers:
- You may do about ~1..2 refills for the same (non-reffillable) toner cartridge. After that the cartridge stops working  properly (the quality drops, it may indicate "empty toner" or so)
- The problem is not any chip or so (I haven't seen any at all so far in laser printers), but the problem is, the toner cartridge contains a kind of pocket for "waste toner" (it collects the residuals of the toner that does not jump from the selenium drum to the paper, filth from the paper,...). And this pocket becomes full and starts to spill over. This is then detected by the circuit (it causes leakages on the HV drum excitation and that is sensed by the circuitry) and often reported as "Empty toner" warning. And of course, this situation degrades the print quality really considerably.

Theoretically it is possible to renew the cartridge by emptying and cleaning this pocket before the actual refill, but it is extremely messy job and because of the very high danger related to static electricity combined with high flammability of the dust not really safe to do without proper equipment (metal, highly antistatic desk, with proper vacuum and air filtration).
But on many places you may found shops offering "renewal" of the print cartridges - they do exactly what described, but they usually have that jig to make that job safe. Plus thez are able to replace the drum, if really worn out.
Very frequently they claim to "replace the drum and that is, why it is so expensive", but in reality the drum itself cost about $1 to $2 (so nearly nothing). The money they ask for is mainly to pay the messy cleaning job...

With newer printers the waste pocket problem becomes more severe - it really becomes very close to be the cartridge life limit.


The more expensive high volume printers have separate cartridges for the waste (otherwise the principles are the same), but there we are talking about machines sold for $2000 and above...

At work they replaced the old Lexmark printer with a Ricoh about a year ago.  The toner cartridges for it seem to be simple plastic jug with no contacts that I could see.

Most "smart chips" aren't that smart and can be easily bypassed allowing you to refill the toner.

The problem with this is two-fold. Firstly it invalidates the warranty and (b) I have never come across a refilled toner cartridge that works properly.

I used to have a HP 2605dn printer and decided to get refilled cartridges. They leaked toner all over the place and effectively ruined the printer. I would never use refilled cartridges again; ok so new ones are expensive, but a new printer is even more so (well usually..)

If the toner leaked, they either didn't seal the refill hole they melted in the toner cartridge with tape and they used the plastic plug that came in the kit, or they more then likely didn't empty the toner waste compartment, which takes time and a vacuum, and if the printing was not clean I'd be leaning towards the waste compartment was full.. And an awesome source of cheap laser printers is government surplus I've seen color lasers going for give away prices and not little home use printers but monsters that do like 100 pages a minute and have three paper trays holding 5000 pages each and stand about four feet tall from the floor, and I don't know about the UK but around here they seem to replace printers every two years or so and some have very low page counts.

While it's a pain I wouldn't let a bit of toner in the printer to cause me to throw it away, just take it outside with some canned air and a dust mask and give it a good cleaning, and keep the image drum out of the sunlight, and replace the fuser wiper blade and vacuum or brush the high tension wires..

All of which is a pain in the proverbial rear end and to my mind not worth the hassle just to save a relatively small amount of money.

I have no intention of risking ruining an extremely expensive business MFD for the small economy of refills.

No, I don't have an unlimited budget, but I do have a need for reliable and quality printing.

I hear you, if you have a new printer and need quality print jobs for customers, but if someone needs a good print job with a cheap / used laser printer refills are a good option and if they are done correctly they are just as good as factory new print at a fraction of the cost..

Theres an older Black only HP printer on my home network, model 1012n.

I just refilled its cartridge recently using toner from another cartridge from a printer I scrapped and it works fine again. I had to break off some plastic but underneath that, there was actually a cap that you remove to fill it up. I didn't empty the waste, being new to toner mechanisms I wasn't aware there was a waste section, but no matter, its only temporary till a new cartridge is purchased.

I used to refill inkjets I used to have with either food colouring or ink I removed from trash picked printers and thats always worked for me but if left to long they do dry up but didn't matter since the printers were free. Now I rock an old HP laserjet colour printer I got for 40 bucks in 2014 that came with new toner

All this talk of refilling toner cartridges put me in mind of an incident at a large office I used to work in many years ago. We had several big Xerox photocopiers that used loose toner, in other words you didn't have replaceable cartridges as you do now.

Anyway, this machine needed more toner, and the task was undertaken by a girl who had never done it before. Nobody knows exactly what happened, but there was an almighty scream which was apparently heard over all three wings of the building on that floor..! Somehow, the toner powder had gone EVERYWHERE, including all over this poor girl, who was discovered standing completely still, obviously in total shock..! When she moved, the carpet could be seen under where her feet had been, in a clear outline of where she'd been standing..!

I didn't actually witness this incident personally, but it was the talk of the whole building for ages afterwards, and it took ages to clean it all off the carpet  :D

Toner can be very messy. I once changed a cartridge in a photocopier at the university library where I worked. It had a small door that opened when the cartridge was rotated to lock in place. The old cartridge's door broke off when I took it out, and I didn't notice. The new cartridge wouldn't seat in properly, and the rotation opened the door but did not shut it when removed. It made a fine dusting on the machine, on the carpet, the table, the head librarian and myself. We fixed it and cleaned up with a DustBuster vacuum.

I've also refilled photocopiers that have no cartridge. They had a long tube, about six inches diameter and three feet length. It fitted in a door beside the control panel and when rotated, opened up. You had to wiggle it for about 2-3 minutes until it emptied itself in the reservoir. I've never had bad experiences with those, though.

Machines that have a separate waste toner cartridge will stop working until you change it when it is full.

Sometimes photocopiers work so badly it makes you wish you still had an old Gestetner spirit duplicator in a closet somewhere...

Many years ago, while moving offices at the school where my mom used to work, they found some sort of old duplication device.  The closest I could tell is that it was similar to a thermofax, but what I've read of thermofax machines seem more complex than this thing.  It looked like an extra thick version of a flatbed scanner.  In the base, under the glass was a pair of incandescent light bulbs with a reflector below them.  The master document went on the glass, than a carbon-like sheet went on top of the original, than a blank sheet of paper went above it.  The lid was closed and the lights were turned on.  I think there was a timer for the lights that would vary the contrast.  If not run long enough, the copy came out too light and if run too long the copy came out too dark.  It also only worked with single sided originals.  I think it finally went away when the stock of copy sheets was depleted.

That's an interesting concept. Sounds kind of slow, though.

The ones I'm referring to are more appropriately called spirit duplicators. They had a relatively fast copy-per-minute, provided you turned the crank fast enough (although not too fast as you would spray alcohol everywhere and yield very mediocre results). They consisted of a drum onto which the "stencil" (which wasn't really a stencil) was placed. It rotated and through a system of wicks, the sheets of paper would be pre wetted in alcohol and pressed against the drum, making a 'stamp' of the original. They were messy, but not like the original mimeograph, which had thick molasses-like ink.

Yes, we had these at school, they were great fun. The copies came out in purple  ;D

Purple ink was the most popular as it was the formula that gave the best contrast with the least parasitic staining. The masters (which were commonly called stencils) were also available in a myriad of colours, notably black, red, blue, green, yellow. Most schools only kept a stock of purple, though. The ink was in a carbon paper-style sheet that was placed "backwards" behind the master sheet. When you wrote, the pressure of your pen made a mirror image on the reverse of the master. The mixture of wax and ink was then pressed on the pre wetted paper (with alcohol) and dissolved a tiny bit of ink where it was present on the master, and did nothing (or was supposed to do nothing) were there wasn't an impression (so no ink on the master). It was, in essence, a sort of self inking "rubber stamp" the size of a sheet of paper (A4, Letter, Legal, etc). Very cool, simple process that worked even in power outages if you had a nonelectric machine.

Blank master sheets are still manufactured, oddly enough. They have found a new use : tattoo parlours. The tattoo artists use them to make a sketch of the artwork. When the time comes, they wet the skin of the client with alcohol and press the master firmly, which makes a copy of the drawing to trace with the tattoo making equipment.

Now back to the subject : spirit duplicators had no computerised parts so no chip to tell you it had run its course and needed to be replaced even if it was still good... The only parts that needed regular replacing were the wick and a couple of rubber rollers aside from the consumables of alcohol and paper.

Yeah it was neither fast nor high volume, but could work on a plain document.  Think it may have been an early inexpensive home office type of machine.  Wish I could find more information about it.

So not long after I mention that old machine, I walk into a thrift shop and find one.  Don't know if it's the same model (that was 25 years ago!) but it's the same type.  The heart of the machine is a pair of 200 watt Westinghouse eye saving "T" bulbs!

Now to see if I can find the paper for it.  Turns out the final copy was on special paper, not plain paper.

First fax machine I ever had used special paper, it was a Xerox Telecopier 400, it worked by feeding the original onto a roller and it sucked it in and scanned it VERY slowly, I think it took about 4 minutes to send a single sheet  :o

Not only the financial side of it, but also the environmental impact. The machine works perfectly but "we'll replace it because it means a new, more modern one". I'm also very annoyed by this marketing ploy...

Yes, planned obsolescence. I'm suffering the effects of that on my iPod touch at the moment. Not sure what to do to replace it, maybe an iPhone (but that is expensive and would probably result in a monthly bill).

OK, I'm going off topic here.

Another annoyance is the reduction of the ink volume in inkjet cartridges... The first ones I had were the Canon BC-01 and had 28 mL of ink (I think. It was generous, though). It was for an old Apple StyleWriter II. Some new ones have much less ink than that.

We have a Samsung CLX-6260FW, otherwise known as 'The Beast' (https://www.lighting-gallery.net/gallery/displayimage.php?album=4653&pos=34&pid=143861) - original manufacturer cartridges are expensive, we get re-manufactured ones from a company we found on the web, they use original cartridges and refill them, it costs about 150 or so for a full set of extended life cartridges, which last well over a year at the rate we use the printer. The company guarantee them to the extent that if one of their cartridges ruins your printer, they will replace it, which is good enough for me..!

Speaking of planned obsolescence, stay FAR, FAR away from printers that have a 'cleaning' function, especially inkjets. These will randomly start cleaning themselves at anytime , especially after powering on. During the cleaning process they will use some ink to clean the print head nozzle and the ink then gets dumped into large block with sponge inside, designed to last the 'expected' life of the pinter, when the sponge is full and starts to leak, printers EOL. I once had a brother copier, fax and printer- scanner combo machine and it would eat through ink fast. I gave up and started putting food colour in it or salvaged ink until it broke.

Also had an epson inkjet printer given to me, when i tried to refill its cartridges, they still said they were empty so must have had an eprom chip in them. This is like those Dell laptop batteries that just stop being detected and die after a certain amount of cycles, even though it worked perfect the day before. It has an eprom chip which locks out the cells. Replacing the cells does not fix the battery

HP inkjets.... I used to refill those and when I would take the cap off the cartridge, the 3 sections for the colours were not even fully utilized! In each colour section, the ink occupied only a bit more than half the space, the rest was an empty unused pit divided by plastic. There was so much unused space in there by design so the unit runs out faster.

Lexmarks, now those were fun, I could fill them up no problem and the spaces inside for each colour were fully occupied.


Today it seems that manufacturers have caught on about the ink scam, so now they sell 'tank' printers, where you pay big bucks for the printers but not so much for the ink bottles to refill the tanks. But im sure theres still little tricks involved to make you spend money

The inkjet cleaning is a drawback of inkjet technology itself, it does not like storage. I remember in the 90's the printers (at that time very expensive) didnt have any suh function and I really do remember the constant problems with clogged jets, once the printed was not used really daily. So I would be rather happy the automatic cleaning is there. But what still is problem, is the impossibility to replace the waste sponge on many of them.
But the fact is, except the printing head alone, inkjets are extremely simple and low tech machines, there is really nothing worth more than few 10s of dollars, even include all the profit margins of a consumer product distribution chain. The only really technically challenging part is the printing head (the bank of micro pumps and nozzles and the ink distribution from the reservoirs) and its matching with the ink fluid characteristics. But still $70 for few ml of ink is ridiculous and "locking" it by the chips isreally overboard (a knock off ink may give inferior print quality, but it is the customers business if he is satisfied with it for the price or if he uses genuine better quality, but more expensive ink).

With the lasers I observed the prices of genuine new cartridges (drum, toned fill, clean waste compartment in one assembly) did fell down to just very small bit above the prices of the refurbished ones (those are still cheaper, but it is like 30-50% not the tripple or more as it used to be), so the competition is working. I only hope the refurbishing companies wont cheap out (e.g. skip the cleaning,...) too much.

What are you guy's opinions on the mega tank printers they offer today, seems epson and canon have a lot of those. Printers are pricy but the ink is not. Might be a better option there.

I personally prefer colour toner for my everyday printing, I'd go for ink for photos

I generally don't print frequently enough to not have issues with the print head on inkjets clogging up even on printers with a auto cleaning function but the HP colour laser I saved from the e waste bin seems to be going fine. The toner it came with is still good but after it goes I'll probably end up buying generic cartridges for it since my standard for print quality aren't that high. Anything I want nicely printed I'll probably get it professionally done anyway.

Back in the 90's, when consumer inkjet printers were still in infancy, the usually suggested remedy for clogged ink was to print a very large black (or whatever colour gave poor results) rectangle. The unusually high flow of ink was said to unclog the head. I only ever did it once as I usually didn't have that problem. The printer was a Canon Bubblejet rebranded as the Apple StyleWriter II. It used a big, high capacity black ink cartridge (BC-01 if I remember correctly).

In each colour section, the ink occupied only a bit more than half the space, the rest was an empty unused pit divided by plastic. There was so much unused space in there by design so the unit runs out faster.

Lexmarks, now those were fun, I could fill them up no problem and the spaces inside for each colour were fully occupied.


Today it seems that manufacturers have caught on about the ink scam, so now they sell 'tank' printers, where you pay big bucks for the printers but not so much for the ink bottles to refill the tanks. But im sure theres still little tricks involved to make you spend money

We have an HP 930c from the late 90s that still works perfectly. It had exactly that happen to it - sponge overfilled to the point that ink dripped on the table under the machine + was getting on every printed page. I disassembled it, washed out of it a Tom Riddle's diary worth of ink, and it worked perfectly ever since

Today's HP have some "ink subscription" program - basically reporting your ink use for an online "ink license" sorta scheme that informs your printer how much it can still print - I would very much stay away from something like that !
