1 Introduction
This manual is to be used in conjunction with AnaJet SP-200 Sprint 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 their
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 certain components available from AnaJet. They
are not expected to repair components and printed circuit boards. Accordingly this Service
Manual is limited to meet the objectives indicated above.
The majority of hardware used in the AnaJet SP-200 Sprint Printer is English inch series.
There are however a few metric sized fasteners and care must be exercised when
reassembling hardware to insures the correct sizes are installed.
2 Adjustments
2.1 LCD Character Contrast & Backlight Brightness
The contrast in the Control Panel LCD display and the backlight brightness can be
adjusted. Open the printer cover. To adjust the LCD character contrast use a
nonconductive small flat bladed screwdriver inserted thru the Front Access Hole in the
electronics enclosure cover and into the trimpot located on the Controller PCBA.
Clockwise rotation will increase the contrast. As you adjust the trimpot, watch the LCD
display to make sure you get the desired level of contrast. See Photo 2.1-1

To adjust the backlight brightness, use a nonconductive flat bladed screwdriver inserted
thru the Rear Access Hole in the electronics enclosure cover and into the trimpot located
on the controller PCBA. Clockwise rotation will increase the brightness.
2.2 Table Position Sensor Tab
If the printing start position varies or there is mis-registration when printing on black fabric
the Table Position Sensor Tab may be out of adjustment. To adjust the Table Position
Sensor Tab, do the following:
1. Remove the Print Table Assembly by loosening the knob under the table.
2. Remove the Tray by removing the four 10-32 screws holding it.
3.1.Remove the Rear Enclosure by removing the six seven 6-32 screws on the back
panel and the four 6-32 screws on the bottom, if present. Slide the Rear Enclosure
off. See Photo 2.2-1 & 2.

6.4.Observe the location of the Slider relative to the Rear Bumper. The Slider should
just touch the Bumper. If there is a gap or the slider is pressed hard against the
Rear Bumper, loosen the two 6-32 screws holding the Sensor Tab and adjust it until
the Slider just touches the Rear Bumper. Take care to line up the sensor tab so that
it interrupts the position sensors but does not rub against the chassis. loosen the
screws holding the sensor plate and adjust until the Slider just touches the Rear
BumperPress the TABLE key to drive the Slider forward and back a number of
times to insure that the Slider just touches the Bumper when it stops. See Photo

2.3 Encoder Sensor Adjustment
If printing becomes erratic or an error condition occurs check the Encoder Sensor
adjustment by doing the following:
1. Remove the Rear Enclosure cover by removing the seven 6-32 screws on the
flanges and four 6-32 screws on the bottom panel, see 2.2. Slide the Rear
Enclosure off.
2. Unplug the 5 circuit Encoder Flat Flex Cable (FFC) from the Sensor and plug it
into the Adapter Assembly with the contacts aligned with the short 5 circuit FFC.
See Photo 2.3-1
3. Attach Oscilloscope Probes to pins 2 and 4 on the Adapter Assembly connectors.
4. Set the oscilloscope to 1 volt vertical on both channels and 500цs horizontal,
trigger on channel 1 rising, trigger level about 0.5v, continuous acquisition, see
figure 2.3-1.
5. Turn on the unit and press the TABLE key. Continue pressing TABLE to observe
the waveforms.
6. Turn the oscilloscope run mode on and observe the waveforms. The ideal
waveforms are shown in figure 2.3-1. The pattern should be uniform and free of
missing pulses or ragged pulses.
CAUTION
The Encoder Sensor is very static sensitive, use
antistatic protective equipment.

7. Change the horizontal time to 100us. The ideal waveforms are shown in figure 2.3-
2. The pattern should be evenly split between high and low states. The two
channels should be shifted ¼ cycle.

8. If the patterns are not as shown above, loosen the two 6-32 screws holding the
Sensor Mount and adjust the Sensor until the ideal waveforms are attained.
Observe the Encoder Disk through the hole in the Chassis Rear Bracket to insure
that the Encoder Disk does not rub against the three Sensor Mount Guide Pins.
9. When the proper waveforms are attained, tighten the two mounting screws and
reassemble by reversing the above steps.
2.4 Obstruction Sensor
If the Obstruction Sensor becomes misaligned, adjustment is required. To align the
Obstruction Sensor do the following:
1. Remove the cover from the electronics box, see 3.2.10.
2. Turn on the main power switch on the rear of the printer.
3. Check table adjustments and leave table height at the adjustment height. See User
Manual Chapter 4 Sections 6 and 7)
4. Turn on the laser adjustment mode.
5. Place the gage block on the table at the left edge of the table with the alignment line
parallel to & closest to the table.
6. Check the laser vertical alignment with the alignment line. If it is not aligned,
adjust the laser mounting block to align it.
7

7. Move the gage block to the right side of the table.
8. Check the laser angular alignment with the alignment line.
9. Recheck the alignment at the left side.
10. Move the gage block out of the laser beam.
11. Measure the voltage on J 2 pin 14 on the Control PCBA. If the Obstruction Sensor
is properly aligned the voltage will be 0 to 0.5 VDC.
12. If is not, adjust the sensor block vertically until the voltage is correct.
13. If the laser beam is not aligned horizontally, adjust the 2 set screws in the laser
mounting block to align the laser dot in the horizontal plane with the center of the
sensor opening. This may require loosening the laser mounting block screws
slightly to allow movement.
14. Place the gage block to interrupt the laser beam. The voltage should change to 3.0
to 3.3 VDC. If it does not change, check the connections to the sensor and the J2
connector pins.
2.5 Lubrication
2.5.1 Linear Guide Rails
1. Lubrication of the Linear Guide Rails is needed for every 100 Kilometers (62
miles) of travel. This is equivalent to about 50,000 print cycles.
2. If the unit experiences this number of print cycles or has been operating in a severe
environment, the Linear Guide Rails may be lubricated with light machine oil such
as 3 in 1 synthetic oil applied to the Rail top and bottom surfaces. See Photo 2.5.1-

2.5.2 Carriage Shaft
1. Normally the Carriage Shaft does not need lubrication. However if the unit has
been operation in a severe environment the Carriage Shaft may need lubrication.
2. To lubricate, move the Carriage to the center of the Carriage Shaft, see User
Manual for procedure to release the Carriage. User Manual, Chapter 7, Section 4
Page 50)
3. Apply a very small amount of synthetic grease to the Carriage shaft on both sides
of the Carriage. See Photo 2.5.3-1
Photo 2.5.3-1
4. Move the Carriage back and forth a few times to distribute the grease evenly along
the shaft.
5. Turn on the unit to return the Carriage to the parked position.
2.5.3 Other Lubrication Points
