Lamp Replacement
AS A ROUTINE MAINTENANCE PROCEDURE, replace the read
lamp after every 1200 hours of operation. This allows approximately a
half year of operation (based on an 8 hour operating shift per five days a
week). Failure to do so may cause erroneous density readings. X-Rite
has also provided you with an extra Transmission read lamp. This lamp
should only be replaced by a qualified service repair person.
1. DISCONNECT LINE CORD FROM POWER RECEPTACLE.
2. Set unit upside down and remove larger bottom cover [1] by
unscrewing the three screws [2] located in front portion of cover.
3. Unplug lamp connector from circuit board (located under small
bottom cover).
4. Remove lamp assembly by unscrewing the two Phillips-head screws
[4] (with washers) from bottom of lamp assembly then discard lamp

screws [4], and two flat washers supplied with lamp.
