Problem

Symptoms: When the customer retrieves a WP 5.0 document formatted for top and bottom margins of 0" and 1" respectively, the printer acts like it was set with a 1" top offset (or text realignment) and overprints the first three lines of text. The only way the customer could work around the overprinting problem was to set the top and bottom margins to 1" at the beginning of the WP 5.0 document. Solutions: This problem is occurring due to a top bias that is subtracted from the margin setting to calculate the top print position. This will not be corrected; it was included in the driver because most people using Epson printers either have a sheet feeder or manually feed the paper. The customer can correct the problem in one of two ways:

1.      Edit the form the customer is using in WP (Shift-F8, 2, 7, 5), and change the Print Adjustment Top from 0" Up to .45" Down. This cancels the top bias.
OR

2.      Edit the printer driver, go to Printer Commands, and delete the given value for Printhead Bias (Top). The customer needs to be aware the printer driver will then assume the top of paper is aligned with the top of the printhead. This may require the customer to manually adjust the paper in the printer and adjust any forms the customer has defined in WP.

These printers cannot print less than a .45" top margin because of the short tear-off feature. For this reason, the proper fix would be to not set a margin less than .45". To make sure this will always be the case, the customer can go into Miscellaneous Numbers in the printer driver and set the default top margin to .45". Changing the top printhead bias is the same as setting a 1" top offset and using a 0" top margin.
