Hi guys.. im going to attend a call on a kyocera 4053ci with a very faint copy quality problem. customer is 215 miles away and there has be multiple calls and engineers out at it. its only 3500 clicks on it and it has had a new HVT/LVT/MAIN BOARD fitted. there is a couple of other same devices at the site so the other engineers tried dif dev units/ drum units and transfer belt unit in it but no joy. they stopped the machine mid cycle and the image on the belt was very faint. Any ideas before i go down to customer. ive worked on Toshibas for 18 years so dont have a lot of experience on these machines. to me the print samples look charge transfer related (NO ERROR CODES ATM).. Thanks in advance

Re: Kyocera taskalfa 4053i very very faint copies
I can't tell much from those image samples.
Does it affect a single color or multiple colors? Are you getting toner add conditions, and what colors? Have you done any adjustments/calibrations? =^..^=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.

Re: Kyocera taskalfa 4053i very very faint copies
I would look for a connection problem between the transfer belt unit and the main frame that might affect the transfer current between the drums and the belt. Either the HV output or the transfer rollers not pressing the belt against the drums properly.Comment

was there a code for low usage on these machines? Would the(image quality) sensors give any probs?
thanksComment

Re: Kyocera taskalfa 4053i very very faint copies
I wish I had something to offer you. The image quality seems to be pretty stable on the series, overall.
I think I'd start with a developer refresh, maybe 2 or 3 times, to see if the density comes back. If yes, the developer is not stirring often enough to maintain the tribo-electric effect. IIRC, there are settings to calibrate more frequently. I'll see what I can find.
If that works, you might try these settings: =^..^=Attached FilesLast edited by blackcat4866; 07-04-2021, 02:42 PM.If you'd like a serious answer to your request:

Re: Kyocera taskalfa 4053i very very faint copies
no worries, hoping its something simple. Maybe the last engineers forgot to push the wee buttons that engages the mag rollers on the dev units lolComment
