Kyocera Taskalfa 4501i Light Printing problem

[aborad]

Hi everyone..

One of our customer are using 3nos of Kyocera Taskalfa 4501i machine. since last few days we found intermediate light printing at bottom of page in all three machine. After switch off machine for 30min or next day its works fine. We have replaced DV , Drum , Transfer Roller and upgrade firmware but problem remain same. i am thankful for suggestion.

That looks like the polygon motor needs to be cleaned. That's usually the case when it's light on the front frame side.

Thanks for your suggestion. We had clean mirror and motor but problem remain same.

If i read correctly you say 3 machines are doing this? I would be putting a voltage regulator not a surge suppressor on one of the machines to see if that helps figure out a power fluctuation especially low voltage output.

Are you sure ? as problem is intermediate. after switch off machine for 30min sometime its works fine for a whole day and sometime we need to Switch off many times. we have clean laser scanner many times.

Are those pages run LEF or SEF? I think we've all been assuming that it was LEF. =^..^=

Re: Kyocera Taskalfa 4501i Light Printing problem

As Blackcat questioned, is it LEF or SEF? Since you stated that you have three of these units at your customer exhibiting the same problem, I would have to assume that it is not an internal machine problem as some of the samples you provided were machine generated reports eliminating any network/computer issues. It is statistically unlikely that you would have three units suddenly have the same issue, a machine problem. As Craigster suggested you should be looking at a potential power problem in the outlet voltage. One thing you failed to mention are these three units in the same location? Renting a power analyser and attaching it between one of the units so it can record power problems could help.

theres a bulletin about the laser not sealed properly

Re: Kyocera Taskalfa 4501i Light Printing problem

is the toner from Kyo?
does it only affect black?
how does u89 sample look?
maybe give black developer a vigorous shake end-to-end and see if there's any effect. might be blockage in dv.
