RE: ACT available
RE: 100 ohm resistor. I actually tried that, with no effect! This is what led me to open up the printer. Looking at the signals at flip flop U5A- they all looked the same from both my HP25E ACTs - attenuation made no difference in the appearance of the signals. I was actually attenuating the signals by placing my finger over the IR receiver diode. This led me to look for bad solder joints, and the M80C50 chip which decodes the digital signals to driver the printer module. The spec for the printer specifies the pulses at 32,768 Hz rate (you know this from the HP82240 interface guide), but that decoder chip had a simple LC oscillator. My experience working on the elusive HP45 hidden stopwatch feature (see my website https://davidreaton.com/hp-calculators/hp-45/ ) told me that LC oscillator frequency can vary widely depending on component values. All the 'Classic" series use a simple LC oscillator to multiplex the display LEDs. I played with swapping capacitors into this circuit to adjust the frequency, with limited success, until I found the MEMS oscillator, which gave the required 784 kHz frequency with only 20ppm drift.

Therefore I measured the frequency at the M80C50 oscillator pins. When I clipped the frequency meter on, the printer began printing flawlessly. I assumed that the RC load from the frequency counter input changed the LC oscillator resonant frequency enough to bring it into spec. I added a 10 pF ceramic cap to this circuit, and now it works well. BTW, the schematics shown for the HP82240A and B models (from Kees Vandersanden's site) show C values of 47pF and 390pF, respectively. I couldn't see the caps values in my printer, so I don't know which one is correct.

To be perfectly honest, I don't know if the LC oscillator modification is the true, definitive answer or not. I know the IR attenuation observation I made, DID WORK, but I don't know why!?? Maybe putting my finger over the IR receiver diode added some stray capacitance? I'm a chemist, not an electrical engineer!

Clipping the frequency meter on made the difference. I guess it's an example of the Heisenberg uncertainty principle. The act of measurement changes the very thing you're trying to measure!

Sorry for the long winded post. It was a long, strange trip, indeed! Thanks for all feedback, help and suggestions.

Regards,

Dave
