[comp.laser-printers] Is it safe to use refilled cartridges for Canon Series II printers?

burton@mitisft.convergent.com (Philip Burton) (08/05/89)

I have a QMS 810 PS printer, based on a Canon Series II engine.  If you have
a LJ II or LaserWriter II NT or NTX, your printer uses the same cartridge.

My cartridge is getting to the end of its useful life.  I can buy a new cartridge
for about $90 discounted, or a refill for about half that.  However, I have
heard that Canon sabotages the Series II cartridges with abrasive filings (?)
so that it is not safe to use a reloaded catridge.

Can anyone on the net comment?  Can you recommend suppliers, or warn about
bad experiences?

Has anyone on the net used successfully a do-it-yourself reload?  Would you do
it again?
