Default Re: Star Gemini-10 printer

Hi Chris, did you remove the Upper Casing?

Pages 49-53, and 262 (actual - not pdf page numbers) describe / picture the dip switches including their locations. In order to access DIP Switch one, requires removing this.

I think the Serial Port pcb came with its own manual, which included its dip switch settings.

User maintenance for this TYPE of printer is simple. With the power disconnected:

a) with the Upper Casing removed, blow out any dust etc. with a Hair Dryer set to cold and maximum blast, Use a long thin soft (childs paint?) brush to assist.

b) the print head moves on one or two rails and generally has bronze or similar bushes.
Remove any dust wads that have built up.
Manually Position the Print Head in the centre of its run.
Place a single drop of quality (eg Singer Sewing Machine or Razor) Oil either side of the print head, on top of the rail(s).
Slowly move the Head to its left and right limits a few times.

c) as you found the printer, check there is nothing inside the parallel or serial ports that might interfere with a signal.

It is worth remembering when these Printers were made, the www did not exist. Thus lengthy Printed Manuals were supplied, packed with information, often similar in size to 'War and Peace'

Regards - Mike
