Wanted: HP-97 power adapter

[Chr Yoko]

I had the very same issues ;-)

For the printer you need to get it out and disassemble it to pieces for replacing the hardened soft plastic drum for paper advance (a piece of tube was perfect on mine).

Be carefull not to loose the tiny "cirflex" shaft locking washers, they have tendency to fly around and to desapear.

My own citation :
"I just fixed the printer paper advance issue by replacing the cracked old elastomeric friction wheels by sections of rubber tube just pressed in. To do so i had to desassemble completely the printer mecanism shafts. It was not difficult. Cleaning and added some silicon oil on the wheels and shaft. Works as new now."
