HELP! I need Head Cleaning Card for HP41 Reader



#4

Can anyone advise where I can buy a HP41 reader head cleaning card. I live in UK so will have to get by post from overseas I guess.

Thanks in anticipation

Take a normal card, douse it with 91%+ isopropyl alcohol, stick it in the reader and and force it past the drive roller. Push/pull it in and out several times. Repeat a few times. Wait for alcohol to dry (a few hours) or blow it out with canned "air" (otherwise the roller will slip).

All this assumes that your drive roller has been rebuilt. If it is original, you will need to replace it first.

Thanks David

The drive roller is original but has had little use I believe. The reader gives erratic results when verifying cards and gives errors when reading data that appears to have been written to it OK. I have checked the cards and there is definately no sign of marking on them by the roller. That's why I want to try a head clean first before considering changing the roller.
