Question about Minolta magicolor 2350 Laser Printer
My magicolor 2350 has suddenly developed a problem printing cyan. Cyan will not print at all unless it is called for at 100% intensity. All the other colors print normally. The side color registration page looks fine except for the cyan row, which is blank except for the right-most square, which printed perfect cyan. Supplies status say all 4 toners are 98% remaining, drum unit is also 98% remaining. Any ideas why the cyan is not printing?
When you print stop the printer half way through then check the image on the opc drum and transfer belt to see if it's complete or not, also you may want to check the aidc sensor (sometimes the cable comes loose). I can e mail you the 2300 series service manual (4.17mb) if you reply with your e mail address

SOURCE: hp 4600 no cyan printing
Firstoff, if you have tray 1 set to "any size" & "any type" they had problems with it going into calibration to frequently. If you upgrade the firmware this will take care of that. As for no Cyan, check the scanner interlock to insure it is opening the scanner cover. You could also go into diagnostics and disable cartridge check and swap the cartridges around, ie. cyan & magenta, run the print quality pages and see if the problem follows the cartridge. It could also be HV power supply.

Order a new "Button", the small part that has 3 contacts that touch each cartridge as they rotate by. It is a small black switch that can be easily accessed by removing all cartridges. It pops out easily, be carefuld not to damage the wires that attach to it. You may find the part at: https://www.nationalparts.com/store/cart/purchase1.asp?pid=6984&XPR=0666058409690586098F076D0B0666058409690589098C076B0B
There is a min. $15.00 charge, so buy 3 of them at $5.00 each, plus shipping, you will spend $28.22 (ground shipping). Works for me!

I think someone touched on this solution briefly, but here is how you fix the problem.
Clean the 3 copper contacts on on the green chip with an eraser or rubbing alcohol. The chip is on the right side of the cartridge. You will probably see black lines on the contacts. This will fix the issue about 90% of the time.
If it doesn't work you want to clean the chip reader. This is the switch that CCSStech was talking about. It also sits on the right side of the printer almost under the toner cartridges and has three prongs sticking up. Clean those prongs with alcohol. If that doesn't work replace the switch. If you are using refilled cartridges, the chip on those sometimes doesn't work. In that case have the manufacture of the refill replace the toner for you.

You might have an issue with the cartridge lockers. Be sure to clean cartridge contacts and HV pins in printer. Doesn't help? Do like this. In the printers menu, under system set up, then print quality, then replace supplies there you can choose override out. Print a status page and check status for the cartridges, if the printer don't prints in override mode you have a brooken cartidge locker. In that case, remove all toner cartridges and check the lockers by moving cartridgedoor in and out, do all works the same way or is any of them different?
