HP 19C carriage return

[Geoff Quickfall]

Hello Katie,

I will check the current and voltage again. The problem is the motor momentum and run time is too fast and long. As though the parked signal is not being accepted. The motor correctly de-powers but the momentum from the RPMs carries it through the parked position and right back into the run mode.

Is there a feedback current that brakes the motor once it starts its return? Is paper thickness part of the braking concept using friction?

Battery contact has been cleaned and tested, perfect. I am going to jury rig a three battery pack and see what happens.

Rob,

Thanks, but the mech, contact switch, spring for the head guide in the helix, in fact the whole damn thing is in perfect mechanical condition. Maybe I greased the helix and shouldn't have?

The guide mech. works perfectly, the motor too perfectly as it is so frictionless the motor passes through the parked position and into the run position again by momentum and not current, alone.

Perplexed me!
