Alpha seting of dfx 8000 printer
The purpose of this adjustment is to set the PG offset value in accordance with the nose dimension
of the printhead. (For details, refer to Chapter 2.)
The offset for the nose dimension is represented by the adjustment value “ALPHA.” The “ALPHA” value
is stored in the memory on the main board, so the PG adjustment mechanism can read the value as
needed. Be sure to perform the adjustment when required. If this adjustment is not performed correctly,
the platen gap will be incorrect, the paper could be caught by a head pin, or, in the worst case, a head
pin could break.
NOTE: The printhead adjustment value is written on the front of the head unit (refer to Figure 4-2). After
the printhead is attached, the value cannot be seen. Be sure to write down the value before
attaching the printhead.
Step 1: Connect the AC cable. Mount the ribbon cassette, and load paper into the front tractor.
Step 2: Turn the printer power on while pressing the LINE FEED, MICRO FEED (V), and PAPER SELECT
