Kyocera is the quality of the final model is quite lowered .. you what do you think about this ?
The Alphard 2 range seem much better, but still poor quality, we sell Sharp Copiers as well and overall build quality is much better , but even sharp machines aren't as good quality as they used to be, seems everyone is cutting costs somewhere, found on the Kyocera machines that they use poor quality clutches and cause intermittent jamming issues. The 7750ci we had the problem with had every thing replaced and we still coulnt crack it , very frustrating . we replaced the machine with a 7551ci and all is well, not had the problem on any other of our machines.
Anyone find an answer to this problem besides replacing the machine?
I'm having same issue with a 4550ci except that problem also occurs on other colors (Not just black). Customer runs much more full color than black & white.
Have replaced drums and dev units. Inspected transfer belt and ID sensors.
Running calibration seems to fix it but often returns in less than a day.
Have noticed that machine is logging error code 7601 very frequently. This error is logged only and is not displayed - You must check error history to know if this is occurring. Initially I was thinking the 7601 (Front ID Sensor Error) was occurring due to the density dropping out. That it was a symptom and not the problem. Now I am thinking that the ID sensor or a connector / wiring maybe causing the problem. Has anyone else noticed this error when problem occurs?
Thanks for any input or thoughts.
I also had similar problems like this with light prints on some colours.
It was a verry easy quick fix.
After you replace Main charge rollers or complete drum with Main charge roller yoiu have to reset U930
This was the problem on many of the machines.
After reset restart the device and do all calibrations in this order
1. Firmware the latest
2. Altitude adjust (if needed)
3. Colour calibration U464
4. Colour registration U469
5. Tone Curve adjust U410
6. Uneven density U412
I know this is an old topic but still worth the info
