Operating the BID Washer
The Control Panel
The control panel is located on the front BID Washer wall, facing the operator (see Figure
2-2). It contains the following:
●A circuit breaker
●The BID Wash Cycle rotary switch has Short and Long wash cycle positions, in
addition to a neutral center position. When either the Short or Long wash cycle is
selected, both the pump and the BID motor are turned on, and imaging oil flows to the
BID. The Long wash cycle is used when replacing a color. The switch contains a
green light that is on during normal operation, and which flashes if there is a problem
such as an open door or a low imaging oil level. Return the switch to the neutral
center position when the wash cycle is complete, which is indicated by the green light
turning off.
●A lit Tank Oil Level Low red light indicates that more imaging oil should be added.
After adding imaging oil, the red light will flash. Press the Tank Oil Level Low
push-button for three seconds to turn off the light.
●A lit Filter Congested push-button indicates that a filter needs to be replaced. After
replacing the filter, press the push-button for three seconds to turn off the light.
●Operating the unit in the Manual Wash mode turns the pump on and directs imaging
oil flow to the sink. The pump will continue to run until the switch is turned off. The
switch contains a green light that is lit during normal operation, and which flashes if
there is a problem. Return the switch to the neutral center position when the wash
cycle is complete, which is indicated by the green light turning off.
●When operating the unit in the BID Inching mode, the pump is off and the developer
roller in the BID is rotating as long as the BID Inching switch is in the on position. The
upper BID Washer door may remain open during this mode of operation. The BID
Inching switch contains a green light that is lit during normal operation, and which

Maintaining the BID Washer
The BID Washer uses imaging oil for cleaning. The imaging oil system in the BID Washer
is a semi-closed system. Imaging oil flows from the imaging oil tank to the cleaning sink,
to the tank wash station, or to the BID Unit, and then returns to the imaging oil tank. Two
filters, located at the imaging oil tank outlet, filter out the imaging oil impurities. When the
imaging oil filters are too dirty to filter the imaging oil, they should be replaced.
The Tank Oil Level Low red light on the control panel indicates the imaging oil should be
replaced. After adding imaging oil, the red light will flash. Turn off the flashing red light by
pressing the Tank Oil Level Low push-button for three seconds.
Refilling the imaging oil tank
Requirements: Imaging oil (see the HP Indigo part number on page 23).
Frequency: When the Low Level light is on.
The BID Washer imaging oil tank capacity is about 15 liters (4 gallons). The imaging oil
tank supplies the sink (in Manual mode) and the BID (during the Long and Short BID
Wash and the Tank Wash) with fresh imaging oil. Once the imaging oil tank level goes
below 10 liters (2.5 gallons), the Tank Oil Level Low light turns on. Perform the following
procedure to refill the imaging oil tank.
1Open the BID Washer front doors (see Figure 2-2). Note that the lower left door must
be opened first, as the two lower front doors are mechanically interlocked.
