To prevent clogging a t th e n ozzles d u e to foreign ma tters , n ever tou ch th e n ozzlesection of th e BJ ca rtr idge or wipe it off with t issu e pap er or the like. For th e BJ
cartridge, take the s am e care with th e ink fi lter of th e print h ead b ody to prevent poor
ink su ction du e to foreign ma tters . Also, once you h ave removed the head ca p an d
peeled off th e protection ta pe from a BJ cartridge, either insta ll the BJ cartridge in th e
printer or s tore it in th e cartridge con tainer to p revent clogging a t th e nozzles du e to
ink drying or foreign objects . Do not reins tall th e removed print h ead cap a nd
protection tap e on th e BJ cartr idge. For the BJ ca rtridge, eith er ins tall i t in the
printer with th e ink cartridge ins talled or s tore it in th e cartridge container. If the ink
cartridge is n ot attach ed, poor ink su ction du e to ink drying or foreign ma tters can
occur . BJ car t r idges cann ot be disass embled, assemb led, or washed.
If clogging at th e nozzles or poor in k su ction occur s, h orizont al white lin es

3. PRECAUTION FOR SERVICE
3.1 Precautions Concerning the Memory DataThis printer coun ts th e total waste ink am oun t for the black BJ cart ridge and t he color
BJ car t r idge an d s tores these da ta in th e EEPROM on th e control board. Observe thefollowing precautions during servicing.
1) Checking EEPROM data
The n u mber of sheets pr in ted is counted an d s tored in the E EPROM to show the
printer operating s tatu s. This data can be printed by test print 3 (Ripple pat tern
print).
The waste ink qua ntity dat a is also s tored in th e EEPROM. This dat a is u sed to
indicate a wast e ink full error to prevent ink leaka ge if th e am oun t of waste ink
abs orbed becomes full.
2) When replacing the control board
If th e cont rol board on which th e EEPROM is mou n ted is replaced, the qua nt ity of
waste ink abs orbed mu st be set in the EEPROM by visu ally checking the am oun t ofwas te ink absorbed in to the absorber from behind th e pr in ter ba se un it .
If it is n ot set , th e waste ink fu ll error is not d isplayed, an d ink ma y leak.
3) When replacing the printer base unit
If a wast e ink fu ll error is displayed an d th e printer ba se u nit is replaced, th e waste
ink am oun t data in th e EEPROM mu st be set to zero. If it is n ot set to zero, a wast e
ink full error is displayed an d th e printer s t ops operating before the waste ink
absorber is filled with waste ink.
After th e EEPROM is rest , the da ta i t contained ca nn ot be printed ou t with
a tes t pr in tou t .If you wan t to check th e s tored data , be sure to execute test print out
before resetting the EEPROM.
When the s tored da ta is rese t , both th e to ta l cou nt of pr in ted sheets an d
th e total wast e ink a mou nt will be reset together. Thes e sett ings can not
be reset individually.
4) Rewriting the flash ROM
The flash ROM on th e cont rol board serves as th e cont rol section of the printer. In
earlier models a s ocket type m ask ed ROM ha d to be u pgraded b y physically inserting
a n ew u pgraded mas ked ROM. The flash ROM can be rewrit ten an d h ence upgradingha s b een facili tated.
When flash ROM needs t o be upgrad ed, a FD conta ining the up grading program will
be dis tributed. Using this FD in a comp u ter, the flash ROM of th e printer can be
u pgraded. In order to rewrite th e flash ROM, both the printer an d compu ter need to
be set in th e rewrite modes.
For details on ch ecking th e mem ory dat a with t est print a nd for clearing
them , see Part 3: 3.6 EEPROM Data Setting (page 3-23).
When operation is s topped for th e waste ink full error, ha nd le the pr inter
as explained in Part 5: 5. TROUBLESHOOTING (page 5-5 ).When rewriting the flash ROM, refer to the settings in Part 3: 3.7 Rewriting
the Flash ROM (page 3-26).

3.3 Precautions for Disassembly/AssemblyThe printer is ma de by combining man y plastic par ts . When d isassem bling the printer,
be carefu l not to bra ke or bend p lastic hooks.
Take s pecial care n ot to rip or bend th e flexible cables when removing an d reinsert ing
them on th e contr ol board a s th ey are very thin a nd frail. Also to preventmisconn ection, m ake su re the cab le is fu lly inserted in th e conn ector.
Details of disass embly and reas sem bly procedu res ar e given in th e Parts Cat alog.
Some of the plast ic parts contain glas s fibers for extra r igidity an d
precision. Du e to their inflexible na tu re thes e plastic hooks b reak eas ily.
Use a p recis ion screwdriver or th e l ike for disass embly, and do not a pply
excessive force to release a h ook.
