Chosen Solution
I’ve had an HP8750 for many years. It is currently inoperable, as the print cartridge will quickly slam to the left and stay “stuck” there. I get an error message. Tried cycling power several times, and different sizes of paper. Help!!!
The problem may be with the timing strip that parallels the carriage bar. It is a metal strip with narrow vertical openings, a light sensor counts the openings to figure out where the print head is at to print. Turn the printer off and see if you can move the print head freely, take a lint free cloth dampened with alcohol (you can use an alcohol first aid prep pad) and clean the timing strip and also see if the sensor is blocked as well. The combination ink and dust tends to clog the strip and the print head is not able to sense where it is.
To detail clean the timing/sensor guide stripe; use gun cleaning kit supplies. and · 8.2 Inch Nylon Tube Brush Pipe Cleaning Brushes · 100pcs Foam Tip Cleaning Swabs Sponge Stick for Inkjet Printhead Optical Lens · Puritan Anti-Static Foam Swab, Pointed Tip (0.43In.
