CP2025 "Sticky Solenoid"

[east2100]

It's me again - east2100.

Yes, there's another solenoid on HP CP2025/M451 which seats at the most right of pick-up roller shaft.

Seat CP2025 on its real side then you can see pick-up roller clearly. The solenoid seats at right most of the pick-up roller shaft, the solenoid controls the turning of the pick-up roller. If it gets sticky it will turn the pick-up roller more than one time and gets paper extrusion and wrinkle and jammed at paper entrance.

You cannot see it directly because it hides itself under a black plastic.

Use a pencil cutting knife hotted by fire and cut off the black plastic by 2*2cm or 2*3cm. Then you'll see the solenoid seated at there. It's not the same as the one seated at top right which caused 59.C0, that one' opening is up to upside, but this one's opening is up to downside.

Every solenoid has a spring on itself to keep working. You can try to take the spring out and put the V-shape into where it can work, but in this way you might lose the spring and the L-shape metal.

What I did myself is not to take anything out from the  solenoid but by trying to insert the V-shape paper (narrow one) through the gap between the L-shape metal and body of solenoid. Insert two V-shape paper from both sides of the spring.

After all was done I tape the plastic back which was cut off with black tape to cover the hole which I cut.

Don't ask me it will work or not,off course it did I'v done these on many HP CP2025/M451 and it never lets me down.

Sorry for my poor English, we speak Taiwanese in Taiwan (not Thailand!).

It occurred to me that I have forgotten that there's the 3rd one which seats itself  at bottom side of tray 1 (muti-purpose tray)

Still cut and covered with black tape.
