I have a canon multipass MP370 printer. I am having trouble changing the ink cartridge. They will not stop in place where I can remove and replace.

You are low on ink. Replace all ink catridges

you have to take it so that they could fix it because i think there's something wrong with it from inside ?

The ink cartridges are
not installed
or a non-supported ink
cartridge is
installedi
or the ink cartridges are
not installed
Check if supported ink
tank(s) is installed, and
re-install them properly,
and then close the
scanning unit.

After you opened the front panel, did you lift the scanner section? The scanner section has a switch on it that activates the ink tank holders to come out to the middle so they can be changed. It is not the greatest design and it doesn't stay up by itself. I normally use an old cartridge to prop up the scanner section while I change cartridges. Hope this helps!

yaa thats your black Print Head is not working, you need to get it replaced by new print head.

thats only solution.

Normal 0 Driver could be corrupt.
Disconnect the printer or at least be sure it is turned off. I'd do both and reinstall the CD software program that came with the printer. When the software program asks you to connect the printer to the USB port, do so and it should again work properly.
Hope this helps. Bud

take out both ink cartridges, lift up head clip and take out printhead block

stand printhead block in a shallow dish of windex overnight, rinse it off, place back in printer, replace ink cartridges

do a clean cycle

The real problem is that the waste ink tank is nearly full

Correct code procedure for resetting the Canon MP370


Reset Waste Ink
1) Enter SERVICE MODE.
By pressing the black button
with the star (in a
head ?) above it, followed by
scan, copy, scan
2) Select TEST MODE (press right
arrow button 13 times).
3) Select [8] PRINTER TEST
4) It'll now say "- 8-2 +" press
the right arrow key once
to get "- 8-3 +" Hit ok.
5) Select 0. [INK COUNT].
6) Press the ok key.
7) It should return to showing
the "8:
Printer Test - 8-3 +"
8) Press the [Stop/Reset]key -
black key with triangle and
circle on it –
(returning to the state of 3)),
and then press the [ON/OFF]
key.

Good Luck and don't blame me if it
goes wrong !!!!

Now you can print again, but it has not solved your full ink-tank, that has to be solved in future.

I have the exact same problem, cleaned heads, replaced cartridge, nothing prints, no ink at all no colors or black.

Don, have you unplugged the printer for a few minutes? first the power plug, see if that clears it. If not, unplug it from the computer, reboot the computer, then plug printer back in. If not that,when an ink cartridge is refilled (depending on the model) the printer needs to be tricked into thinking a "new" cartidge is being installed. They make their money from the ink, not as much the printer. You may need to check the owners manual to see if the is the case. I have had to use tape to block off certain contacts, then remove the cartidge and block off another section of contacts, then remove tape all together and re-insert the cartridge.
