pg-10.jpgAuto G 5180.jpgBeen working on this Canon C5180. It was all set for a while, Now the Cyan is dropping out on copies in random areas.Tried New Drum, New Toner, All ITB Cleaning and adjustments etc... Please look at the Auto Gradation sheet this is printing. You can see the Cyan Trouble. Any Thoughts? Greatly appreciated.ThanksDave

remove side cover over Manual Feed> to view ITB when doing these test prints> observe lay down on ITB
check Drum ground tab position- Check and clean the drum ground tab located inside the front drum access cover.

3200.jpgSeems to come and go so perhaps the Drum ground tab will do just that?Comment

seeing that PG10/ U need to check your CYAN primary charge roller position inside the ITB unit/
make sure the end shaft is locked in the black plastic tab/spring loaded catch and is not damaged

OK....I Swapped the Laser. NO CHANGE..
Printed out a New Cyan PG-5.
Notice the top Drops out approx 1/8 of an inch AND Then it is Darker at the top and slightly fades light as you go to the bottom of the printout?
WOW... This is driving me Crazy!!!!
Somekind of communication problem I suspect???

Re: Canon C5180 - Cyan Dropping out of copies?? See Attached PLEASE
Remove small side cover to view ITB>run the PG5 CYAN> look at ITB SHEET>is the image fade off visible on sheet ??
if so> remove ITB & ITB SHEET> inspect that CYAN Primary charging roller position> sometimes they look level> have u replaced this roller before ??
if pg5 cyan image is solid on ITB> before separation>suspect the HVT 1 for Cyan or swap connectors with another color--
if fade is after separation >suspect the HVT 2**Knowledge is time consuming, exhausting and costly for a trained Tech.**Comment

At some point you need to swap the lasers back or swap the values for both colours,
The values are also written on each laser.Comment
