It is held in by a retaining lever on the top of the transport carriage. It is the lighter gray plastic piece on top. Follow it horizontally across to the right and the level to flip it up is on the right side of the transport towards the top. Just grab it and flip it up and then remove the print head assembly.

I own 2 canon i9900 printers,they are both 5 years old.maintenance is allways an
issue with this type of printer because of the eight cartridges.If you dont use this
printer for a long time it will dry out at the cartridge depending where you live.
humid temps will keep nozzles wet,if you dont print alot during winter when it gets dry they will dry sooner,keep it active at least once or twice a month ,print a full
size photo of yourself.If you have tried everything after a nozzle check and deep
cleaning and you photos are printing real strange colors,DO THE FOLLOWING
open the cover,the print head will park in the center,get a small flaslight and
shine it inside all the way to the right ,you will see two OBLONG allmost square
objects,That is the PARKING AREA FOR THE PRINT HEAD,you need to clean
that area,use a paper towel and fold it about the size of that area,fold it 3-4 times
to get extra soaking power out of it,next cut it about 3-4inches ,soak in water
sqeeze out paper towel and apply it to the parking area,you will notice almost
right away how black it is,repeat this as many time you have to until that area
starts getting white again,allso clean the whole track on the bottom left to right
in the machine where travel of the printhead accures,the bottom part looks like
foam,clean all that also.Next you can clean the whole printhead if you do not
get proper results after cleaning the parkig area.Open cover and put the print
head and ink cartridges in the center park position.PULL UP ON THE PLASTIC
(GRAY IN COLOR) Printhead retainer,(Make shure all the ink Cartridges are
pulled out,Next straddle your first finger and thumb across the bottom of the
printhead(THE WIDTH OF THE PRINT HEAD) (between PM6 and 6Y) and pull
up gently.NEXT to clean!Get a small container like Glad or Tupper Ware plastic
and soak the whole printhead in WINDEX,depending on how much ink and ink
hardning hase accured it is all different times for soaking,try 3-4 hours or over night,After a good soaking put on paper towel to drain.DO NOT TOUCH THE
BOTTOM OF THE PRINT HEAD by wiping it,gently set it on a paper towel and do not move it back and forth,let gravity drain it!Put back the Printer head and
ink cartridges,you will have to recalibrate and align heads again,nozzle check ect
some of the fluid from your cleaning process might show up for the first 1-3 sheets of paper so dont panic,all runthe low level cleaning process that the
printer has.If all this fails you will have to replace the printer head they run about
$120-130 USD,ther are plenty of sites on the net selling this product

Good Luck...............SK Florida

A printer,s ink pad is at the end of its service life

This means the waste ink collection sponge is full. This counter can be reset but it is strongly recommended to replace the ink pad as you will end up with a large amount of ink spilt on your desk if you continue to use the printer after the pads lifespan. It can be quite a large job to change depending on the model. If the printer is not an expensive model it may be more cost effective and less messy to simply replace it with a similar model.

My Epson WF-3640 is printing with gaps in the text. How do I fix this issue?

Make sure you should remove shipping tape from the ink cartridge. These taps are used to protect printer during shipping but you have to remove it before starting printing. Beacuse these taps prevent the ink to entering in print head. If you will not found shipping tape in your printer then there is terr off strip, remove it. The tear off strip seals the the vent holes on the top of the cartridge to prevent it from drying out on the shelf or during shipping.
After ensuring that the shipping tape has been removed, run the printer's "Head Cleaning" utility to prime the cartridge, then print a test page.

How to clean ink absorber for canon mp237

First of all open the ink cartridge of your printer.
When the ink cartridge would move all the way over, then disconnect the power cord of your printer.
Now pull the frame of rubber from the printer and remove ink pads.
To clean ink pads you may place them in a bowl having warm water and start rubbing and squeezing them to clean it from ink.
After removal of ink, keep the pads separate for dry.
When the pads get dry completely, place them back in rubber frame.
Reinstall the rubber frame in your printer.

Printer won't recognize cartridge

I had the same problem. I'm not sure but I think I replaced the cartridges when the printer was on because I turned the printer off and removed one of the cartridges. When I turned the printer back on it recognized that cartridge but not the others. I turned the printer off again, rmoved all cartiridges and put them back in when the printer was still off. When I turned the printer on again I had no problems. So...try turning off the printer, rmove all cartridges, then put them back in and restart printer. Hope this works for you .
