It is recommended that the lamp starters be
replaced when the lamps are being replaced. The
lamp starters are located in the ballast panel in
the back of the machine. For ease of removal and
replacement, a portion of the ballast panel cover
must be removed to expose the starters.
Printer feed belts may become slack over a
period of time, causing slippage and blurred
prints. A simple adjustment may be made as
1. Pull the small Tygon tube out of the
ammonia supply bottle cap.
2. Run the machine until the tube is pumped
dry and no longer feeding the ammonia tank in
3. Raise the motor end of the machine a few
inches for a moment for complete drainage.
4. Shut off the machine.
5. Tip the machine on its back carefully so
the ammonia tubes and power cord that project
from the back will not be crushed or kinked. This
will expose the two slotted idler take-up brackets.
6. Loosen the two screws in both brackets,
and press down approximately one-fourth in,
beyond the previous setting to give proper
tension to the belts, and re-secure. Make sure that
both brackets are set at the same position.
The components in the ammonia chest are
readily accessible and easily removed. The top
cover is removed by sliding a door-catch type of
pivot and then lifting it off of the machine. The
back chest panel can be removed independently
for internal inspection by removing four screws
and sliding the panel out of the machine. Both the
upper and lower paper combs are attached to the
back chest panel, allowing for inspection and
replacement of their combs when the panel is
removed. Take out the ammonia tank first. The
ammonia tank is independently removed from the
ammonia chest by removing the two wing screws
on the right-hand end of the machine where the
tank drains. Disconnect the Tygon ammonia in-
feed tube in the motor end of the machine, and
slide the tank out to the right. The grid and drive
roll assemblies are easily removed as a unit by
unscrewing the plastic drive-roll plug at the right
end of the drive roll. Slide the drive roll off of
a pin slot connector to the drive shaft, and lift
the assembly up and out of the chest.
After 600 hr of operation, the plastic Tygon
tube in the ammonia pump will need to be
replaced. Extra tubing is supplied with the
machine for this purpose. To replace a tube,
remove the left-hand end panel by removing the
screws holding down the drive-section top cover.
This will expose the pump with its motor and all
the tube connections. Study how the tube is placed
so that after it is removed you can place the new
There is a tube coupling on the tube support
bracket. Pull the tube lead to the pump from the
Jog the machine by snapping the power switch
ON and OFF. The old tube will move out of the
pump by normal rotating pump action. Pull this
tube off of the ammonia feed pipe leading into
Take a piece of replacement tubing and cut
the end on a bias (slant) so it will feed through
the pump smoothly. Feed the tubing into the
coupling end of the pump and jog the machine
(as before) so the tube will be pulled through the
When this tube is completely in the pump, cut
it to length and reattach as before to the ammonia
coupling and ammonia feed pipe.
The upper faceplate and the developer feed
plate extrusions are removed by removing two
screws from each and lifting them off of the
machine. This will expose the lower slider gasket.
The lower slider gasket is attached to the gasket
retainer angle and is removed as a unit by
removing the fastening screws. A replacement
gasket unit can then be inserted.
TROUBLESHOOTING. If the Blu-Ray
machine is to operate at peak efficiency, it must
be kept in proper working order. In trouble-
shooting the machine, use the following summary
as a guide:
Loss of printing speed:
Glass cylinder dirty.
Voltage too low.
Fluorescent lamps dirty or past useful life.
Overage sensitized paper.
Machine not level, causing binding.
Printer drive belts loose.
Air entrance blocked, causing lamp
Flickering or burnt-out lamp, check
