Question about Canon Office Equipment & Supplies

Open Question

I have a Canon Pixma MP750, which I've had for a while. The print function isn't working properly - it's not printing colours correctly, and now the grayscale printing is faint, too. I've tried to do a 'maintainence check, but it doesn't give me any clues as to what to DO about the problem. And the 'auto head align' comes up with two black blocks either side and blank inthe middle, and a message telling me that the 'Align Head Failed'. What now?

SOURCE: OfficeJet G85xi cartirdges will not align

Could be one of two things....

1 - you may have bad cartridges (usually the color)...when the machine does an alignment it looks for specific marks on the paper...ie..green check marks before each line etc...if the correct marks are not there you will get an alignment failure...if the green check marks are there etc then you have a different problem...first replace color cartridge with a HP Brand cartridge

2- spot sensor on the side of carriage is not working...this is the little blue/green light that comes on during alignment. Its what reads the markings on paper so if the markings are correctly there and you still get this error then the spot sensor needs to be replaced. Simple fix that u can do. We sell the spot sensor for $15

Run the alignment test page from the software on your computer and check and adjust the alignment.

How do i clean the printhead on my pixma mp750


If you open the preferences option for your printer there should be a maintenance tab with easy options for cleaning and checking the results. The alternative is to use the menu directly on the printer: 1. Press Menu twice to show "2. Maintenance" 2. The first option is NOZZLE CHECK 3. Press OK This should give you a print showing the current state of each colour. If there are any missing lines in 3eBK or lines in any colours then perform the head cleaning below. 1. Press Menu twice to show "2. Maintenance" 2. Press + to show "CLEANING" 3. Press OK Repeat the nozzle check after each clean. If not improved after three attempts try a deep clean as below (cleaning uses up ink) 1. Press Menu twice to show "2. Maintenance" 2. Press + twice to show "HEAD REFRESHING" 3. Press OK Repeat the nozzle check. If still not printing correctly there are various external solutions available to clean the print head such as http://www.printheadhospital.co.uk/canon-hp-printhead-cleaning-kit.html

Canon MP750 not printing


I had a similar problem. I put in a new ink tank but did not seat it properly. When I tried to print nothing came out. Worse yet, apparently it burned out those jets in the print head! A new print head fixed my problem. I got it on eBay and am very satisfied.

Will not print in black


Sounds like a driver configuration. Go to control panel, then printers and right-click properties on the Canon icon, try reverting to default print settings or make sure you are not forcing color printing. Lastly, try printing from a simple program such as notepad - maybe your software inputs color to the printer.
