9820/9830/9835 Service Manual

Functional Description

RS-232 interface

This interface allows connection to devices capable of RS-232 communications. The interface is incorporated in the microcontroller and has DIP switches to set communications parameters. The DIP switches can be set manually by the user or through software control.

Centronics IEEE-1284 Parallel Interface

This interface accommodates high data rates, up to 2M Bits/Second.

IEEE 1284 Bi-Directional Parallel Interface

An IEEE 1284 High Speed Bi-directional Parallel interface provides parallel communications. The microcontroller directly controls the port. The interface allows compatibility with the Centronics interface as well as allowing for High Speed Bi- directional communications.

NOTE: Third party LAN devices are connected through the parallel interface to allow the printer to interface different LAN networks.

Contrast Control

A manual contrast control, located at the edge of the Control Board Assy., extends out of the rear cover. It is used for fine adjustments to the print contrast values.

Hardware Power-up Settings (DIPS)

Two 8-switch DIP switches, located on the back panel of the printer above the contrast adjustment, control the default power-up configuration of the printer. Settings include the serial port settings, diagnostics, ribbon setup, printer mode and supply type.

Peel Module Assembly

The peel module separates the supply from the backing paper. It consists of an on-demand sensor, rollers, and a 12Vdc motor drive. Dip SW1 (switch 2) located on the daughter board enables and disables the peel function.

PRINT ASSEMBLY

This Print Module is a plastic casting located inside the printer’s hood. It is attached to the mid frame by two bearing blocks which capture studs on the module back plate. Components of the Print Module are:

Figure 2- 1. Print Assembly

Thermal Printhead

The printhead is located at the bottom front of the module. It is held in place by a plastic carrier which acts as an interlock to a formed metal bracket. The bracket is center-mounted and pivots to ensure an even pressure on the supply. The printhead bracket has two alignment loops which slip over the platen roller to assure dot row to platen roller alignment. The printhead mount also has two spring loaded adjustment knobs to adjust printhead pressure for wide or narrow supplies. A 30 pin ribbon cable connects the printhead to the Control Board Assy

Ribbon Supply & Take-up Spools

The ribbon supply and ribbon take-up spools are located on the supply side of the module. Each spool shaft extends through the module wall and connects to its own DC drive motor. The spools are designed to handle a detented ribbon core so when ribbons of various widths are installed they maintain center justification.

Ribbon Transfer Rollers

Two ribbon transfer rollers are located on the supply side of the module. The rollers are ribbed and attached to metal shafts by retainer screws. One sits at the very front of the module wall above the printhead while the other is positioned just above the supply deflector.
