RDY/MODE: Places printer online or offline.
CHK-F/L: Clears fault status after minor malfunction, i.e., jammed paper/ribbon,
out of paper, and forms thickness.
8LPI/ADDR: Changes to alternate line spacing, i.e., 6 lpi (default), 8 lpi, or 10
lpi.
TOF/DATA: Advances paper to TOP-OF-FORM or single line feed. (Press and
hold for TOF and press and release for LF).
2nd FUNC: Secondary Function: Allows the previous four switches to have
alternate functions, i.e., RDY becomes a printer mode switch, CHK becomes a
forms length switch, 8LPI becomes a printer configuration address change switch
(ADDR) in the numeric display LED, and TOF becomes a DATA switch to select
one of nine option for configuration address changing.
Note:
See “Configuration” for more details on how to use this switch.
Self-test
1. Lift the printer cover. Ensure that the RDY indicator is flashing.
2. Press the 2nd FUNC switch (inside the printer).
3. Press the ADDR switch; the indicator will stay on steadily. A code on the
digital panel (under the red stripe) will show two digits. If this is the first use
of the ADDR switch after the power has been turned on, 00 will show; otherwise the last code will display:
00.1 Prints the printer's configuration.
00.2 Prints the style of character set ordered for the printer.
01.1 Prints 8 tests which include the alphabet, underlines, and individual
02.1 Prints the letter "E" continuously.
03.1 Prints a rotating alphabet.
letters.
Cover Removal
Upper and Rear Covers
1. Turn power off and unplug the printer from the wall socket.
2. Lift the upper cover up and lock it into place using the hinge lock mechanism.
3. Unscrew the top cover from the hinge brackets and carefully lift up and set the
cover to the side.
4. Lower the back cover, then swing the open card cage which is held by a magnetic latch at its right hand end.
5. All internal parts are now accessible to the printer.
LEDs/Lights
RDY: When lit, indicates printer is online. When flashing, indicates printer is
offline.
CHK: Flashing = minor error and steady = service required.
When lit, indicates service is required. When flashing, indicates a minor error.
8LPI: When on, indicates alternate line spacing has been chosen. When off, indi-
cates 6 lpi (default).
TOF: When on, indicates TOF has been set.
2nd FUNC: When on, indicates secondary function choice has been selected for
the RDY, CHK, 8LPI, and TOF switches. When off, indicates standard function for
these switches has been selected.
DISPLAY: A three-digit display used to show configuration choices and five (5)
operator error codes.
Configuration
The MVP 150 Printronix printer uses a combination of keys, i.e., the 2nd FUNC,
ADDR, DATA and RDY to set up the configuration which are displayed as
addresses on the numeric display at the left of the operator's control panel. The
entire three-digit configuration display is in the form XX.Y where:
XX = The two left digits from 00 to 99 and .Y = the third digit from .0 to .9
Note:
Addresses 00-19 are test and service printout addresses. Addresses 20-99
are configuration addresses. Table 1 is the procedure to change configurations,
and Table 2 on page 2 are the default settings:
