1.5 Terms and Abbreviations
The following list shows the major terms and abbreviations for the MFP.
Terms Abbreviations Explanations
Automatic Duplexing Unit ADU Paper whose front side was printed is reversed so that
its back side can be printed.
P. 2-1 “ 4. Paper exit section and reverse section”
Application Specific Integrated Circuit ASIC This is a downsized and exclusively designed IC with
multiple functions (circuits) integrated into one chip.
B
usiness Service Instruction BSI This provides information and instructions related to
maintenance to service technicians, separate from the
Service Manual.
Capacitive touch panel - Capacitive touch panel
Charge Coupled Device CCD In order to scan images, a CCD image sensor is used
in the scanner for the MFP.
P. 2-2 “[ 1-1 ] CCD”
C
ontact Image Sensor CIS This is an image sensor which is smaller and has a
more affordable price than a CCD. This is used in the
scanner for low-end MFPs. The capability to focus on
areas far from the original glass is low.
P. 2-2 “[ 1-2 ] CIS”
Copy Per Minute CPM Number of sheets for copying which can be processed
per 1 minute
Developer material - Fine powder in which the toner is included in the carrier
coated by a special resin. This transports the toner.
P. 2-11 “ [Developer material]”
D
ocument Feeder DF This is a collective term for original feeding devices
such as RADF and DSDF.
D
ual In-line Package Switch DIP-SW This is a small size switch with terminals embedded
and is mounted on the PC boards. This is called a “DIP
switch”.
D
ots Per Inch DPI This is the unit of the resolution and refers to the dot
numbers per 1 inch (approx. 2.54 cm). A larger value
makes the dots finer and gives a higher resolution.
Dual Scan Document Feeder DSDF This option separates the original sheets, slightly slides
them and then transports them one by one to the
scanning position of the MFP. A scanner for scanning
the back side of the original is embedded. Due to this,
both the front and back sides of the original can be
scanned at the same time in one original feeding.
E
lectrophotographic Process Unit EPU This consists of the developer unit, main charger unit
and drum cleaner unit.
P. 2-6 “[ 2 ] Overview of the color process”
Finisher - This option exits printed or copied sheets of paper
having sorted and stapled them.
Fuser unit - This unit fuses the toner (images) transferred onto the
paper by means of heat and pressure. This also is used
to erase the toner color in the s-STUDIOxxxxLP series.
P. 2-15 “2.3.10 Fusing”
I
nduction Heating IH This is a heating method using electromagnetic
induction and is used as a heat source in the fuser unit
of the MFP.
I
mage Quality Control IQC This function is mainly equipped in color models. This
optimizes the conditions of image forming in order to
minimize the variation of the image density and tone
reproducibility caused by the conditions of use and the
life of the consumables. The toner is used to form toner
images on the transfer belt.
P. 2-15 “2.3.11 Image quality control”
Jig - This is a tool exclusively used for adjustments.
P. 4-4 “4.3 Jigs”
