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
Photo 2.3-1
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
and Photo 2.3.3 below.

5. With the pulley bracket loose you can now adjust the tension by moving the pulley bracket foward or back
until the required tension is achieved. Once adjusted tighten the screws back to hold down the pulley bracket
in place and measure the tension using a Gates belt tension meter. The specifications for the table motor belt
are below.
Mass (M) 001.4 g/m
With (W) 009.0 mm/r
Span (S) 0047 mm
............................................................................................................................................................
The correct tension for the table motor belt is 9 to 12 n (32 to 43 ozf). Measurements should be made at
several positions of the pulley to account for any eccentricity.
Please note: When adjusting the tension on the table motor belt you will
have to also re-tension the table belt again. Please see section 2.2 for
instructions on how to tension the table belt.
6. Retighten all screws and reverse these steps to place back your table assembly into your printer. Don't
forget to re plug all cables back to the table board.

2.4 Carriage Encoder Adjustment
Tools Needed
o5/32 Allen Key
If excessive abrasion occurs or if the Carriage Encoder is replaced, you will want to check the position of the
encoder. If adjustments are needed follow the steps below.
1. Begin by releasing the carriage (Menu > Maintenance Functions > Print Carriage Control > Release
Carriage). Once the Carriage has been released move the carriage to the far left. Observe the position of the
encoder strip, the encoder strip should be going directly down the middle of the encoder sensor. The encoder
should not be touching or leaning toward one side. Move the Carriage to the far right now and check the
position of the encoder strip on the far right side.
Photo 2.4.1
2. If adjustments are needed loosen the two socket head screws holding the left encoder mount and adjust
until centered. Retighten the Screws. See photo 2.4.2
Anajet mPower i-Series ServiceManual

Photo 2.4.2
3. Now that we have adjusted the left hand side, move the carriage to the far right and check the encoder
strip alignment on the right side. If the Left side was adjusted its possible that the right side has moved and
needs adjusting. If adjustment is necessary loosen the two socket head screws and adjust the encoder until
we have the correct position. See Photo 2.4.3
Photo 2.4.3
4. Once the encoder strip has been adjusted secure the carriage back to its home position.
2.5 Wiper Height Adjustment
Tools Needed

oPhillips screw driver
1. Begin by releasing the print head (Menu>Maintenance Functions> Print Carriage Controller >
Release Carriage).
............................................................................................................................................................
2. We must now remove the print head cage from the carriage. There will be 6 phillip screws
holding the cage down.
3. In order to make the proper adjustment you will need to move the wiper blade to its "engage"
position. Press ENTER + JOBS + MENU at the same time to go into the technical menu >
MODULE TEST > MAINTENANCE STATION > WIPER BLADE ENGAGE. The wiper blade
should now be moving forward to the wipe position. See photo 2.5.3
See Photo 2.5.3
............................................................................................................................................................
.. 4. Once the print head has been released use your Anajet Wiper Height Tool and place it on the
left hand side of the carriage. The wiper blade tool will have a groove where you can place the tool
on top of the nozzle plate. See photo 2.5.4 below.

.... 4. If the wiper blade is too low or too high you want adjust the wiper blade by loosening the lock
screws on the left and right hand side. See image 2.5.6. Once the lock screws are loosened you
can adjust the height of the wiper blade with the adjustment screws. Moving the adjustment screw
counter clockwise will drop down the wiper blade and moving the adjustment screw clockwise will
raise the wiper blade. Its Very important that both sides are even. There will be an Adjustment
screw on the left and right hand side. Once the wiper blade has been adjusted to the required
height, lock the position in place by re tightening the lock screws. See image 2.5.7

2.6 Table Z Axis Motor Limit Flag Adjustment
Tools Needed
o3/32 Hex Key / Allen key
oFlag Measuring Shim (P/N - 150620-001)
Begin by releasing your carriage. (MENU>MAINTENANCE FUNCTIONS>RELEASE CARRIAGE.
Go to the technical menu (MENU+ENTER+JOBS). >Module Test>Motion control>table up. This will raise the
table to its flag limit. See image below.
Use the Flag Shim measuring (.030cm). The shim will have a limit tab to stop you.The shim should fit
perfectly underneath the carriage. If the table is too low we will have to raise our flag limit, or if its the shim
doesnt fit at all we will have to lower our flag limit.
2. Remove the table assembly. The table assembly will have 4 3/32 hex screws. Once the hex screws are
removed the table should be released. See Photo 2.6.2
Anajet mPower i-Series ServiceManual
16

Photo 2.6.2
3. Remove the bottom plate. No screws will be removed from this plate, simply lift up. See Photo 2.6.3
Photo 2.6.3
4. Newer printers will have this skirt covering the tables scissor lift. Older printers will not have this skirt. If
your table assembly has a skirt remove the 8 screws below to release the skirt. See Photo 2.6.4
Anajet mPower i-Series ServiceManual
17

Photo 2.6.4
5. The tables limit flag will have 2 phillip screws. Moving the Flag towards the printer (inside) will raise the flag
limit. Moving the flag backwards (away from printer) will set the flag limit lower. The flag is very sensitive and
moving the flag too much can lower or raise the table excessively. See Photo 2.6.5
Anajet mPower i-Series ServiceManual
18

Photo 2.6.5
6. When the flag is adjusted re assemble your table. Use the 4 hex screws to level your table. Loosening the
screws will raise your table up tightening the screws will lower your table down. Use the shim and adjust your
screws as needed. If the flag was moved too much you will have to remove your table assembly and adjust
your flag again. When adjusting the table top do the measurements from both sides on the left and the right.
You will also want to check all corners when you move one side as the other side can potentially loose its
position. See Photo 2.6.6

2.7 Obstruction Laser Sensor Adjustment
Tools Needed
oPhillips Screwdriver
oLaser Gauge
The laser sensor can only be adjusted once the Table Z axis motor limit flag has been adjusted see section
2.6 Before adjusting the laser you will need to have your printer updated to the latest firmware.
To adjust the laser we must first check the current height using the laser shim measuring (.060 cm). Once
the laser height is adjusted we can now adjust the laser to be pointing straight. The final step is to check the
value of the laser which should read 1023.
1. Laser height
Turn your laser on (laser on under technical menu). See photo 2.7.1
Photo 2.7.1
Hit the table down option under the technical menu as this will move your table all the way down, then hit
table up this will raise your table to the current laser height. Use your shim and decide if the laser needs to
be adjusted. If the shim is loose, the laser has to go up, if the shim does not fit between the carriage and the
table then the laser has to go down. See Photo 2.7.2
