ImagePress C1+ weak Yellow

[mynameis]

Hey guys.

A customers C1+ suddenly droped down in density of yellow.
First changed developer filling -> no change.
Then changed developer unit, and developer filling -> no change.

Strange thing besides that: When initializing Yellow, E020-0586 appears, which refers to the clear toner dev....
Second attempt to init works.

CM and K are all good...

Any ideas?

Recallibrated RIP - no change.
Strange aswell: After INIT the fresh DEV, yellow gets even paler.
Yellow is now at approx 20% density, when printing PG5 with 255 dens-Y

No one an idea?

Performing a Developer Change on the imagePRESS C1 or imagePRESS C1+/and Clear Developer. see pdf

some techs skip steps------------

E020 - 0586 error code is indicated after replacing Y/C/M/K starters.
This error code is referring to the Clear Toner (L) patch which is not measured at the referenced value by the patch image read sensor.


In a couple of cases, replacing the Clear Toner starter resolved the error code.


Developing BIAS Input Assembly resides on the front plate of the P-Kit.
When the Developer Units rotate and are positioned for development, the BIAS tab rubs against the Developing BIAS Input Assembly to receive the developing BIAS.
The part number is FM2-2662-000.





primary and secondary transfer rollers

Thanks Teckat.

Wouldn't the Developing BIAS Kit, aswell as primary and secondary transfer rollers affect all colours - and not just one?

did u follow procedure on Starter Replacement ? or did u wing it ?

Yellow unit must make contact with bias tab on rotation

Is Y Dev> receiving Y Toner


Full Area Half Tone (TYPE=5) what does that look like for Yellow

Followed the procedure exactly.
Checked contacts..seem fine.
Tried 2 different dev units, same result.
PG type 5 looks like 10-20% dens max, when sent with 255 value - barely visible.

How would i check if the dev recieves toner? Tape the input hole and perform SPPLY-Y, then check if there's toner on the tape?

u have any error codes in history ?
does it look like toner is on Y DEV MAG ROLLER ?
should be a rich yellow & not a washed out metallic look

Thanks Teckat.

Programmed the DENS Values from the door, then made a few blank copies. Yellow went better and better..
Now it's all up and running again.

Seems like it was an air bubble in the toner transportation?!?
