Re: What does "CH" mean?
On the Sharp copiers when the "ch" is blinking means that the toner cartridge is not in or it may be the wrong cartridge. Some sharp cartridges look alike and will fit into the machine but are the wrong one.

that is because ur head of ur printing cartridge is damaged.
remove ur cartridges black as well as color
n install only black cartridge n check d blinking of lights on ur printer if it doesn't blinks it's mean ur black cartridge is OK but ur blinking of light on ur printer is same it's mean ur head of black cartridge is damaged
after this process remove the black one cartridge and install the color one cartridge n check d blinking of lights on ur printer if it doesn't blinks it's mean ur color cartridge is OK but ur blinking of light on ur printer is same it's mean ur head of color cartridge is damaged
now take a dry cotton cloth n gently clean ur cartridges head
install both cartridges on ur printer n check ur blinking light on ur printer
that will work only if u r too lucky other wise u have to purchase a one cartridge.
Hi, In all type of sharp copier there is tow type of ch code , if you have blinking ch that mean you have Check the developer unit re insert it probable i, if you have stead CH that mean you have to check the door properly there is an open door . than you for using fixya
probably you need to download the driver for windows 7 in the canon website.(www.canon.com.sg) if this doesnt solve your problem check the led and display of your printer. if the led blinks alternately in orange and green it means that your printer needs to be brought to an authorized service center for resetting and diagnostic.
CH - open cover in the paper feed area
CH blinking - Dev unit is not properly
For the 'CH' check the covers and make
sure all covers are closed properly.
For the 'Blinking CH' take the dev.
Unit open and the reinstall unit properly.
Pls rate – thank you
