RE: HP 10 printer issue
Hi, All

Good news. The problem has been solved.

The root cause is that I use a NPN transistor to replace the Q2 which should be a PNP transistor.

Now I have a perfect working HP 10.

After this HP10 repairing, I gained a lot of experience and help from others.

Thank you everyone.
