Resetting an Epson C1900/C900 photoconductor unit?

Archived from groups: comp.periphs.printers (More info?)

Does anyone know how to reset an epson photoconductor unit which is
still printing OK?

After only 8000 pages, and while it was still printing perfectly, my
C1900 announced that the PCU needed replacing and refused to print
till I had obeyed its command.

Epson say that a PCU should last about 45000 pages.

Does anyone know how to reset either software or whatever it is on the
PCU that counts pages or assesses area printed.?
This is totally stupid and another example of how the computer
industry is getting away with behaving very aggressively towards the
consumer.

Sorry, you've missed the point - I had to replace a unit which was
working perfectly.

The reason that the color number is about 25% of the black one is
because color printing requires four passes of the PCU for each page.

Bad customer service from Epson? Do you live in the UK by any chance?

I can appreciate having a printer give an indication of consumable
wear, but to prevent a consumable from being used based simply on a
calculation is pretty lame. They should allow the user to continue
printing until the component physically stops working, I don't see why
it should damage the printer to do so. Have you spoken to the consumer
watchdog about this? If they agree that it's unfair, they can issue a
court order for manufacturers to stop this practise.

It seems that the printer companies are all stuck in this consumable
business model. They make the printers with every possible system to
confound using consumables beyond the arbitrary dates they conclude will
require replacement.

Some actually have a fuse built into components that is surged at a
certain life point to make the component no longer function. Many
printer companies make fallacious claims that they are protecting print
quality or other components, but it tee case of the OPC drum, I know of
many people who have the fuse replaced or just replace the fuse with a
link (which actually might remove a safety feature) and the drum and
printer continue to run perfectly fine for many thousands of extra copies.

I recently discovered that a Minolta Laser printer I bought, once the
toner cartridge empties, somehow reprograms or burns a fusible link or
something so that although it can be refilled, the printer will run at
1/4th the speed with a refilled toner cartridge.

I haven't heard Konica-Minolta's excuse for this, but I can bet it will
be something like: our printer is designed for the toner we use in the
cartridges. As such we know that those toners do not require extra
cleaning cycles between prints, but with other toners, to preserve print
quality we give the drum 3 extra cleaning cycles per page.

Of course, this is completely fallacious. However, it does two things,
one, it slows the machine to the print that some people may choose to
use OEM cartridges to maintain the speed, and secondly, the extra
cleaning cycles tend to both wear and scratch, as well as weaken the
photosensitivity on the drum, making it fail sooner, and the drum is
even more costly than the toner cartridge.

I am very seriously considering speaking to some political contacts I
have about developing legislation for Canada to outlaw this type of
garbage (literally and otherwise) on an environmental basis if nothing
more. The EU has already done so in a number of areas.

If you put 4500 blank pages thought an Epson c900 it will tell you the toner cartridge is empty. C900 use a cog every time the printer run the cog moves in the end it hit the top and presses a sensor which then reports it needs a new toner cartridges. I have found a way without re-moving any screws on the toner cartridge to push it back to the bottom again.

As for the drum just remove the fuse or replace it with a 1 amp household fuse. The fuse blows because its works on a cog system to the opc drum moves a cog every time a page goes though when it get to the end the fuse blows.

The Epson c900 print engine is made by Minolta
