Replacement QF1 MOSFET transistor for printer mainboard repair. The QF1 transistor works with the F1 fuse in the printhead power circuit, switching the power path from the printer's power supply toward the printhead driver circuitry. If the F1 fuse has blown due to a printhead, cable, ink contamination, or electrical short, the QF1 transistor may also be damaged and should be tested before replacing the fuse alone.
Common Uses
Replace a damaged, burned, missing, or shorted QF1 transistor
Mainboard-level printer repair
Repair damage caused while replacing the F1 fuse
Troubleshoot printhead power-circuit failures
Useful when the F1 fuse repeatedly fails or the printhead receives no power
Installation
This is a surface-mount electronic component and requires board-level soldering experience. Hot-air rework equipment is recommended for removal and installation. In our repair process, the original component is removed with hot air, the pads are cleaned, and the replacement is installed using solder paste and hot air.
Important
Replacing QF1 does not automatically repair the underlying problem that caused it to fail. Always inspect and test the F1 fuse, printhead, printhead cables, connectors, and surrounding circuitry before powering the printer back on.
Package Includes
1 × QF1 MOSFET Transistor
Sold individually as shown.
Professional installation is recommended. This component is intended for technicians and experienced DIY electronics repair.

Best thing ever!! i used to put cleaning solution in the capping station with a syringe/hose then had to suck out f the wast line with a syringe.... over and over until the capping station was clean. maybe up to 10 times. now i just use maybe 1 or 2 - 30ml syringes full of water and the pump cleans it out so good.... then I put capping solution, place printhead over capping station and turn on the back of the machine. thats it. when i print again, usually next day, I pull from waste tank a few times until I get ink, then i run 1 head cleaning , print a test strip and usually good to go. I sometimes print a 2nd test strip. SO MUCH easier to use this little pump. so glad I bought it.

This is a must have modification to save time troubleshooting. You will need to download Kevin's capping station video to disassemble the capping station. A definite must. You will also need a few other connections to hook this up. All parts are linked in his videos. Pro tip. Have patience and go slow. This modification will save you from a lot of headaches . I did this mod on Procolored L1800 about a year old . Thanks Kevin.
