If you do not have a densitometer choose the Standard Color Cal Measurement page method under set-up. Use a clean Gray Scale positioned in the top center of the letter size portrait area of the platen glass.
Press Calibrate and Yes to print the Measurement Page.
Place printed page over the Gray Scale and press Yes and then done to measure.
After successful measurement press Yes to overwrite and to it affecting all users.

This is such a common fault on this model. The transfer belt slips caused by leaking toner (usually from the black drum) all you’ll need to remove the transfer belt & clean the INSIDE of it & also clean the large rubber drive roller, make sure you clean both these items well., then do a DC CON CLEAR ONLY.
The machine will correct it’s self after either a full auto gradation or a long colour copy run, or as you are doing open & closing the left fuser draw.

Thanks Teckat. I should have the greyscale. Get back on this

Canontech: The ITB has been replaced and dcon / gradation done as mentioned earlier but thanks

I hope all your ITB bearings are good.

that Large metal ITB cover causes a lot of CQ issues> especially streaks

I take them off & throw them in the Garbage----have thrown away hundreds
leave small one on
but u need to connect other side of the varistor from small metal cover under leaf spring (because no screw hole available) ( not doing this will cause an error)

update on c3200 offset.

with many of the checks and resets done we now have a smaller offset and lighter as well.

The c2 did not allow us to run calibration. would not read anything we put on the glass. I am getting the firmware to reload and try that again.

In scan/copy mode text quality it is non existent. In graphics mode offset present.
sending print jobs in text mode is very light but evident.

if your calibration page color block alignment is offset / printer will not calibrate

this goes for Printer Auto Cal & Fiery Cal

the ITB needs to be removed and inspected as well as the Lasers need to be aligned to their home position

got it. the copier is getting replaced with a loaner. Due to the lack of time in the office to do all checks and adj. we are looking forward to having it inshop. The customer has no patience as the existing service company has been at this for 2 months before we came in. to be continued
