RE: HP97 The journey begins
Hi all,
I attached some pictures of the HP-19C during assembly. Closing the clam shell cases did not present any problems, the connector fingers slid into the respective holes easily. I still don't know if it is the paper, but the printer is still a bit faint. I have overdone the PCB traces for all the power wiring, and the scope shows the proper waveforms to the print head, so there is not much more I can do. The newer paper that prints in black is a bit better. Turning up the intensity setting helps as well. I added another programmable code - [BEEP] [f][f][3]. This can execute in normal run or after adding to a program, from a running program. The beeper will sound briefly after this executes. It all 'seems' to work. I'm going to make a start on the help document. cheers Tony |
