The following tests provide powerful tools to ascertain the operational status of the printer. When

instructed to insert paper: DP8 => 6 x 11"; DP9 => 8.5 x 11"

900 Function - Print Function 92 & Function 93 Settings

This test is used to compare printer and communication parameter configuration between printers

or against the customer's standard settings. It exercises almost all of the printer mechanism and

electronics without requiring communication with the host system. If it prints correctly, reported

problems are likely to involve incorrectly set parameters or the printer to host system interface.

Insert paper into the printer. Press the 9 0 0 FUNCT. The printer will print the firmware part

number, revision, printer configuration index, both the printer and communications parameter

names and current settings and a printwire test. A sample of the 900 printout appears on page 8.

90 Function – Electronic Diagnostics

These tests check firmware, RAM and sensor operation. Electronic diagnostics may be executed

by pressing 9 0 then FUNCT. The following messages will be displayed:

After the RAM test, SENSORS will be displayed. Details on the sensor test can be found on the

sensors page above. Press A key to conclude this test.

95 Function - Local Printing

In addition to Self Test Function 900, one can print several variable length lines without host

commands. Proceed as follows:

1. Insert a form manually or automatically and then press 9 5 FUNCT.

2. In response to CHAR LENGTH = 30, key in a two digit number of characters per line

and then press ENTER. Insure that printing will not occur across a fold or document

edge.

3. In response to LINE COUNT = 01, key in a 2 digit number of lines.

4. Each time ENTER is pressed, that number of lines will be printed.

5. Press EJECT to eject the document and CLEAR to clear the display.

97 Function - Horizontal Passbook Demo

No data entry is required but the printer MUST be in EMULATION MODE 'C' and AUTO

CARRIAGE RETURN "Y" (9 3 FUNCT Parameters see pg. 4). Insert a horizontal fold

passbook at least 5" wide and between 6 1/2" and 7 1/2" high when open. Then press 9 7

FUNCT. Using a vertical fold book or a smaller horizontal fold book will print off-copy and may

damage the printhead.
