Samsung Xpress M2020 Proshivka Fix

[Andrew] was getting ready to print out an assignment when a red error light at him. Unable to find any documentation explaining the issue, he called Samsung directly and found that it was indicating the toner cartridge was nearly empty. He held down the button that prints a test page, which came out just fine despite the printer’s insistence that there was not enough toner left. Annoyed at the fact that he felt Samsung was trying to strong arm him into buying another pricey toner cartridge, he looked for a way around the restriction. He discovered that his printer’s software allowed him to specify a custom test page document, though it required that the document be in PostScript format. After a few shell commands, he had his document converted and was on to bigger and better things.

While a bit time consuming, his workaround should let him get by on this toner cartridge at least for a little while longer. We imagine that since he’s using Linux, the process could probably be scripted to save time, though we’re not sure if the same can be said for Windows-based PCs. • • • • Posted in, Tagged,,, Post navigation.

My HP color laser printer will print any document in the queue when you first power it on regardless of the toner status. The process is: 1) turn off printer 2) print document 3) turn printer back on. It has printed hundreds of full color pages since it “ran out” of toner. I forgot exactly what model, if anyone wants to know I’ll post it up later when I get home.

HP can suck it, if they were honest I would consider buying their official toner but now I’ll probably buy some generic stuff from the interweb or a refill kit. If you call tech support and tell them you put a new toner cartridge in but it still won’t print they’ll give you the command sequence to input to “reset” the page counter and let you continue to use your current cartridge. Unfortunately, laser printers require this so infrequently that you’ll probably forget by the time you need to do it again. However, fortunately, laser printers require this so infrequently that you’ll probably forget by the time you need to do it again. That said, there’s an argument that using a toner cartridge too long past its expiry risks damaging the machine because it requires higher and higher voltages to print successfully. I forget the exact science but it’s a pretty safe risk, probably.

Every time you print a page on a laser printer then a small amount of toner gets wasted. Older printers used to have a seperate container for collecting this. Every time you put in a new toner cartridge then you would put in a new collection bottle (it’s not usually suitable for recycling because it’s contaminated with dust from the air and from the paper, plus whatever else happens to be floating around that part of your printer, and so won’t for sure take the electrostatic charge needed to make the process work). But some cheap laser printers don’t have a seperate container for this waste toner and just mix it back in with the new stuff. When the “cartridge empty” comes on it doesn’t mean that the cartridge has no toner left in it, just that the stuff left in there has (by calculation based on some average numbers) a highish proportion non-toner crud mixed in.

Are their calculations done giving a more than generous safety margin to the manufacturers? I’ve no doubt that the answer to that one is yes, but you should be aware that print quality does deteriorate over time if you force a cartridge to print a long way beyond its rated life, and that there is a risk of biggish lumps of this crud causing more problems. Usually, laser printers (at least the ones I’ve dealt with)use a sensor to ‘see’ how much toner is left in the cartridge. You can usually find this sensor by removing the cartridge and checked the perimeter where it sits. I sometimes just cover that sensor with a piece of black electrical tape so it thinks the toner is always full.
