HP Scitex FB700 Industrial Printer - Manual (Page 65)

● Minimize the quantity of cleaning liquid used during maintenance to avoid spills, contamination,
or harm to printer parts. Carefully moisten cleaning cloths or swabs with the cleaning liquid, and
ensure that none of it drips onto the printer. Any excess or residual liquid should be removed by
cleaning the area with a dry cloth. Failure to clean off any residual cleaning liquid could cause
damage to the printer, or could adversely affect the printer’s level of image quality.
● Disposal of waste must be in accordance with applicable regulations.
Replace UV lamp bulb (500–1000 hours)
The UV ink curing lamp bulbs will gradually emit light of diminishing intensity with use. To
compensate, increase the power setting to the lamps. (From the control panel Media Page, press
Wizard, then press Print Mode Specific Settings.) The UV lamp bulbs are warranted for 500 hours,
but by operating them at low power initially, and increasing the power only when necessary to ensure
a full curing of the ink, a service life of 1000 hours is possible.
Replace both bulbs at the same time, so that both bulbs emit light of equal intensity. Order quantity 2
of HP product number CH231A, HP UV Replacement Bulb Kit. The replacement procedure consists
of these parts:
1. Removing the lamp housings from the carriage
2. Removing the old lamp bulbs
3. Installing the new lamp bulbs
4. Re-installing the lamp housings
Remove the lamp housings
1. From the control panel (System page > Tools > User Cleaning and Maintenance), select
Replace UV Lamp Bulb or Bulbs.
The control panel asks whether you want to proceed with changing the bulbs.
2. Press Yes.
The printer positions the rail and carriage for replacing the bulbs, then displays the prompt,
“Select Lamp to Change.”
3. In most cases, select Both Lamps to replace both lamps (recommended). Otherwise, select the
lamp to change.
4. Press Proceed.
This resets the lamp service hours counter to zero hours. Next, the control panel prompts you to
power down the printer.
5. Turn off the power switch to the printer. Do not disconnect the main power cable from the printer:
this ensures that the proper vacuum is maintained to the printheads, which prevents ink from
leaking out.
6. Wait five minutes to allow any existing current to drain from the capacitors.
7. Open the top cover to access the printhead carriage.
