iPRC1+ Banding line issue

[pga]

Dear all,

Good day. Any ideas to resolve the banding lines issue on c1+? Currently my customer upgrade their c1 machine to c1+,they encountered c1+ banding line issues more obvious than c1. We can easily to see when print PG type 5 or midtone color.

I tried to change ITB unit, drum unit, 2nd transfer unit and ITB drive motor but no improvement at all. Any ideas? is it can be solve?

without seeing samples it will bifficult to troubleshoot on this machine. But with the list of parts you have replaced I would check the drive assemblies...not just the motors. Start with the ITB and drum drive. If the meter count is high the gears are probably worn.

banding has been an issue on these models from the start/ some clients don't even notice

yes. normally we won't let customer see PG type 5 but they can try print any files in 40-50% midtone and all banding lines appear. The Drum/ITB Drive ass'y already changed even is new machine. The system firmware got upgrade to latest but yet no solve.
Some of my customers very concern on it and they may did compared with C1 printout.
I wonder why c1 machine not obvious on banding issue but c1+ very obvious on it.
i tot c1+ will be more better and improved from c1....but.....sad...
anymore advice?

Customer is printing COLOR at 40/50% ! how much paper coverage are u talking about ? if it is over 10% coverage on letter , they should have purchased a imagePress 6000


When u print a PG5 with all 4colors, do u see a rainbow banding effect ???

In some machines the problem is obvious, in other less...
It's an limit of this printer engine......
