Abstract
A system for setting or adjusting the proper registration position of the original document in a copier having a document feeder providing a variable document registration position on the platen, and numeric data key entries programmable in specialized diagnostic modes, and non-volatile memory. The system involves registering and copying a test sheet using the document feeder in its initial, unadjusted, registration setting. The test sheet has a test pattern of registration position indicia with identifying numeric indicia, and also having a registration window at an optically reversed position on the test sheet from the test pattern and a cursor pointing to a specific position within the window. The test sheet is laid over a same-size copy of the test sheet, with the sheet edges aligned, but with the two sheets rotated by 180 degrees relative to one another, so that the copy of the test pattern on the copy sheet underlies and is visible through the registration window of the test sheet, whereby the cursor on the test sheet points to a specific registration identifying numeric indicia within the test pattern copy. By activating a selected diagnostics mode of the copier and then entering the identifying numeric indicia into the numeric data key entries of the copier the copier automatically resets in non-volatile memory the registration position of the document feeder by a preprogrammed distance corresponding to the entered numeric indicia.
