I had a problem with a Canon Pixma TS6360. The ink cartridges would not return completely to the right rest position and it was making a loud click when it tried to do this after closing the printer top. What might have been to blame for this was a leaky PGBK black cartridge, that had been replaced from a shop that has recycled cartridges. The women at the shop said that she would not take any responsibility if this cartridge voided the warranty. It was not me that accepted this, it was someone else that took the printer to the shop. I took the leaky cartridge out and cleaned up with isopropyl alcohol and a clean rag. The white flexible band that connects to the ink cartridges carriage, had quite a lot of ink on it and there was a lot of ink on the carriage itself. I replaced the PGBK cartridge with a compatible cartridge. It did not solve the problem the first time. I had to clean several times more. Finally the ink carriage would return properly to the right hand rest position when the printer top was closed. After an attempt to print the problem immediately returned. I took all the cartridges out and turned off the printer power, nearly giving up on it. Several months later I have put back some new cartridges and the carriage now returns properly and consistently to the proper position when the top is closed. The problem now is that the print heads are blocked. I tried unblocking with a print head cleaning kit where you use a syringe with a rubbery transparent tube attached. The cleaning fluid is called Universal Inkjet Solution. (cannot read the name properly because the label is glued and folded over part of the name). The tube from the syringe would not fit over the inkjets in the carriage. The inside diameter of the tube was too small, so I could not squirt a little fluid through the inkjets without some spilling. I made sure I had a folded paper towel placed under the carriage to absorb any dissolved ink or fluid. The problem returned again where the carriage was not returning to the right hand rest position but it is now solved again by me wiping up some excess spilled fluid with a paper towel. The print heads were not cleared by the cleaning, so I have decided to leave the printer overnight with the cartridges installed, thinking that the ink from the cartridges will dissolve dried ink in the print heads (numerous printer self cleaning cycles have hardly made any difference). When I tried printing a test page this morning it was printing better but still not perfectly. I am thinking I should leave it another 12 hours and it might print properly.
