General Procedures and Information
WorkCentre 3119 06/06 6-23
Paper Size
The WorkCentre 3119 does not have a paper size sensor. If the paper width is narrow, the tem-
perature of the fuser roller does not uniformly conform to the overall surface of the roller. So in
this case, the engine controls the interval of pick up of the paper.
But because it does not have a sensor to determine paper width, it judges whether the width is
narrow by it’s length. If it judges a current paper size is below B5, it regards it as a narrow sheet
of paper. Normally, if a paper size is a narrow, the interval of pick up is lengthened according to
an elapsed printing time and the number of accumulated Printing Pages.
Paper Type
The information of paper type is sent by the main system. The engine considers following paper
types:- Plain paper, Envelope, Label, Bond, Colored paper, OHP, Card stock, Thin, Thick, Pre-
printed.
It controls a fuser temperature and a pick-up time according to the paper type. Each control de-
pends on its mechanism. Normally, papers with larger thickness are controlled by maintaining a
high temperature. But for material like OHP, a lower temperature is used.
Functional Requirements of the Fuser Settings
The fuser settings are managed by the main controller and are determined by several criterias in-
cluding paper type, paper size, elapsed printed time and the number of accumulated Printing Pag-
es. It may also be influenced by hardware specs and inner temperature.
Fuser temperature according to printer status
This printer has 5 modes which are:- warm-up, stand-by, printing, error and sleep mode. Every
mode sets the temperature of the fuser differently.
During warm-up mode, the temperature of the fuser rises up to the warm-up target temperature.
During stand-by mode, it maintains the specified temperature of the fuser in order to reduce the
time to print the first page.
During printing, it controls the temperature of the fuser according to paper type, paper size, the
number of accumulated printing pages, the elapsed printing time and the environment index.
Accumulated Printing Pages
If more pieces of paper are printed, the temperature of the fuser may saturate. In this case, the
engine maintains the temperature of the fuser constantly. The accumulated printing pages are
cleared during sleep mode.
Elapsed Printing Time
If the print job is done over a fixed time, the temperature of the fuser may be saturate. In this case,
the engine maintains the temperature of the fuser constantly. The elapsed printing time is cleared
during sleep mode.
Temperature during Stand-By mode
During stand-by mode, the engine controls the fuser to maintain a specific temperature to reduce
‘first page print out time’. This specific temperature is set according to various enviroment condi-
