Xerox 1000 Drum issues

[makutzi]

Two issues regarding drums:

I recently replaced the magenta drum on our Xerox 1000 with a new one as the old one had some blind spots and scratches on it. Ever since I get error 42-328 (Drum Motor 4 Phase AB fail). The machine would start up and after a few seconds or a bit later come up with this error. I checked the housing and replaced the bearing of the front housing, it seemed a bit "gritty" and then realised that it seems the drum is quite "tight". If the machine stands and i turn the various drums a bit, all turn quite easy except the magenta one. Swapped it with the yellow and the problem fillowed the drum (error 42-328).

Would I be right to assume then that the drum might be faulty? I got another new drum and the same applies. Or could it be that the drum drive of the various colours maybe has reached end of life?

I am sure the Xerox office here will not replace the drum.

The second issue is that also recently I replaced the cyan drum (also due to scratches) and within about 200 prints i noticed a speck on the print in cyan, upon inspection realised the drum had a "blind spot" or a round nick on it which was caused somewhere within 2000 prints - how is this possible, so soon. What can be done to prolong the life of the drums. Has anyone any success with additional drum coatings? I saw an ad on Youtube where they coat a drum with a varnish which extended its life - dicy business i guess.

if I'm not mistaken.. if your drums are OEM and you have record of purchase and they haven't expired .. Xerox SHOULD replace F.O.C. but that is policy in the U.S.

Oh, how very interesting, I will have to enquire about this - normally the guys here at Xerox are not really helpful.

Anyway, I did the following: I dismantled an old used drum just to have a look what is inside and how it operates, then i dismantled one of the two new ones giving me grey hair. I swapped the out the bearings as well as the rubber squeegee. The new bearings were fine and loose but not as noose as the older ones. I cleaned the squeegee with a vacuum and dusted some toner on it for lubrication and reassembled the drum. It was inserted and am going to fire the Xerox up in a few minutes, need to have a coffee first. So the new drum basically got the old bearings and squeegee - and it definately turned easier.

I plan on borrowing an torque gauge to see the actual difference between the "turning".

Getting late here, will post the outcome tomorrow.
