Chapter 1: Introduction
This manual is to be used in conjunction with Anajet mP5i & mP10i Printer User Manual. All
operational instructions, normal printer maintenance and troubleshooting guides can be found in
the User manual. This Service manual is intended to aid Anajet distributor's, technical and service
personnel in providing maintenance and basic repair service to there customers. The services
provided by distributor's service personnel are intended to be limited to the diagnosis, often with
the help of Anajet's Technical Support personnel, simple adjustments, and replacement of printer
circuit boards. Accordingly this service manual is limited to meet the objectives indicated above.
The majority of the hardware used in the Anajet mP5i & mP10i printer is english inch series.
There are however a few metric sized fasteners and care must be exercised when reassembling
hardware to insure the correct sizes are installed.

1. The best way to adjust the tension in the Table motor belt is to remove the entire table guide assembly
from the printer. Before starting power down the printer. To remove the table guide assembly, we must first
unplug the cables connected to the table board. See photo 2.3-1 below

2. Once the cables have been unplugged from the table board we can now start removing the 8 hex screws
holding the table guide assembly in place. Use a 3/8 ratchet wrench to remove the 8 screws see Photo 2.3.2
