A DJ670 is quite vintage now. The paper pickups tend to wear smooth with time - a good cleaner is Isopropyl Alcohol, smeared on with a cotton bud. Then wipe it off with the other end. Let it dry ( a couple minutes) before printing.
Sometimes paper condition can cause issues - paper that has a high moisture content tends to jam lasers, and can cause separator problems in any type of printer. Put a stck of paper in the hot water cylinder cupboard overnight and see if it prints better the next day. If that doesn't help - you need to replace the paper separator unit - and that's probably more than a new printer :-\ I have a Lexmark laser with postscript and NIC to flog off. -----Original Message----- From: Yuri de Groot [mailto:[EMAIL PROTECTED] Sent: Monday, 26 July 2004 9:46 a.m. To: CLUG; NZLUG Subject: OT - Fixing too-smooth printer rollers Sorry this is OT. Well sort of - the printer is attached to a linux box and shared via CUPS (RMS is welcome to ask me how I set it up). Problem: The rollers are worn out. More than half the time it doesn't pick up the paper. This is an HP Deskjet 670C. Does anyone know how to fix this? I have heard you can roughen the rollers up, but I need to be sure I don't wreck anything. Any help appreciated. Cheers Yuri de Groot
