I believe the iR5000/6000 Drums have a life expectancy of 2+ million impressions if I remember my math correctly. Someone please chime in if I'm wrong. If it ain't broke, leave it alone goes the saying with those Canon AP Units.
I agree with copier guy if copy quality is good and the customer is not having any problems leave the drum alone. I have found sometimes messsing with parts that have nothing wrong with them can give you a headache in the long run.
With Amorphous Silicon drums there are two types of failure:
1) Scratches caused by mishandling by customer or tech= 70%
2) Pinholes as a result of Primary charge arcing= 25%
3) Other= 5%
The best thing you can do to extend your drum life is forget its there. Don't touch it unless theres a good reason. Thats good advice for endusers, too.
If you'd like a serious answer to your request:
1) demonstrate that you've read the manual
2) demonstrate that you made some attempt to fix it.
3) if you're going to ask about jams include the jam code.
4) if you're going to ask about an error code include the error code.
5) You are the person onsite. Only you can make observations.
Drums on 5000's not as bad as 8500/105 series... probally also the type of users/customers (105 series mostly print shops who run way out of spec media and way over spec for the machine). Usually spots on your pages are the only real failures I have seen on these 5000's drums. Sometimes you get lucky and its just adhesive/gum and you can just wipe it off (carefully) but if it is a pit, arch-mark, or scratch (by tech dropping screws in the AP kit, or user digging for jammed paper)- you bought yourself a drum. And its not cheap. No non-oem/aftermarket subsitutes that I know. Only other defects are lines (after ruling out the cleaning blade/ap kit) which you can clean the ends/edges of your drums and get all of the crud out and clean the yellow developer rollers that mesh with this area. But, that issue is more common on the 105 series. Make the Drum and the AP Kit your last troubleshooting steps. Always check/replace your Wires, clean dust glass and check Fixing Rollers first. Bottom line- leave them be unless need be.
The glass maybe half full, but less is more...
Printer + Fax + Copier = Jack Of Many Trades,
but Master Of None
Color Copier = Not A Color Printer
InkJet MFP = Not A Fax Machine
B/W Copier = Not A Press
Finisher = Deal Closer (salesman, not accessory)
Copier Tech = Admin's Stress Ball (Scapegoat)
