How to Change a UV Lamp Bulb

Introduction

The  printer uses  two UV lamps, one on  each side of the  carriage, to  cure the UV ink  during
printing. The  bulbs in  these UV lamps have a  limited lifetime and  must  be  replaced by  the
operator if they fail or when they can no  longer cure the ink  at  maximum available power.

When to do

Although the minimum functional life of the  UV lamp bulbs is 1000  hours, there are  factors that
can reduce the expected life.  Operational practices, such  as  turning  the lamps off  and on
frequently, using  them  at  high intensity all of the  time, or  touching the bulbs with  your fingers,
can shorten their life. Océ  recommends that both UV Lamp bulbs  be  replaced at the  same time to
ensure that the curing effect is  balanced when printing in  both directions. In the  case of  a
premature failure or  accidental breakage  of  one lamp, the operator can decide to  replace only  one
lamp but should confirm image consistency after the replacement. Uneven curing can  cause
gloss banding in the  printed image.

NOTE

The  Flatbed Settings  icon on  the  printer interface allows the operator to  control the  power output
of  each UV lamp independently. To  extend lamp life,  use the lowest setting that provides
adequate curing for a particular media. However, avoid handling media with  insufficient curing
as partially cured UV ink  on  your skin can  cause irritation and sensitization.

CAUTION

The UV lamps and the carriage may be hot if the printer has been active. Avoid touching the

lamp assembly until it is cool.

CAUTION

These UV lamp bulbs contain mercury, and if they are broken the vapor is toxic if inhaled. The

lamp bulbs must be disposed of according to local environmental regulations.

How to Access the Lamp Housings

The  housings for the  two  UV lamps are  located on  each side of the  carriage. When you view  the
printer from the end where the Start button is  located, the Right lamp is  located on the  Home side
where the carriage parks when it is not  printing. The Left lamp is  located on the  other (Away)  side
of the  carriage. To  access the Right lamp, make sure  the carriage is in its parked position and
follow the instructions below to  remove a  bulb. To  access the Left  lamp, first  use the printer
interface Tools and Utilities tab  to  move the carriage to  the  Away  end of the  gantry.

How to Remove the Lamp Bulb

It is  not  necessary to  shut the  printer power off the  while replacing the UV lamp bulbs. However,
make sure  you turn them off by de-selecting the lamp icon in  the user interface before you start
and allow a few  minutes for the  bulbs to cool  down.

NOTE

Wear cotton or  nitrile gloves when  handling  UV lamp bulbs. Avoid  bare skin  contact with the  UV
lamp bulbs. When heated, compounds from the skin  can  form permanent etching on the  surface
of the  UV bulb. A contaminated bulb may fail  prematurely.
