HP 67 Card Reader Mag Head - Gene DiResta - 04-17-2003 I have gotten my HP 67 card reader to work thanks to the HP forum response to earlier messages. I have one remaining problem. I can read and write cards from programs programmed in the HP 67, however the reader has a difficult time reading pre-recorded hp strips. I presume there is an alignment issue. How is the card reader head aligned to read the pre-recorded cards ? Any suggestions ?
Re: HP 67 Card Reader Mag Head - David Smith - 04-17-2003 The head was aligned at the factory then glued into place... attempts to fix it will most likely cause more harm than good.
Re: HP 67 Card Reader Mag Head - Tnoy Duell (UK) - 04-17-2003 I would e very suprised if head alignment was the problem. It was never intended to be adjustable (the head is glued in place), and I've never heard of it causing a problem. Re: HP 67 Card Reader Mag Head - Gene DiResta - 04-22-2003 Good afternoon Mr. Smith and Duell,
The card reader's mag head came loose from the plastic holder; the glue must have fatigued. I apologize for not explaining the problem in greater detail in my first request for assistance since I presumed this was a common occurrence, like the "gummy wheel" problem. So I repeat the question, are there any alignment/positioning procedures for the mag head that has come loose?
Re: HP 67 Card Reader Mag Head - David Smith - 04-22-2003 I think that that head alignment was set just by the mechanical tolerances of the plastic housing. One problem in getting the head reset is the head height/card pressure clearance. I have seen some machines fixed by inserting a card in the reader with a couple of ounces of weight on the head while the glue sets.
