General Procedures/Information
DCS Digital Command Signal
DDF Device Description File
Delta TRC Measures the relative intensity between heads at area coverages less
than 100%. If needed, will adjust the image density for improvement.
Densiometer Measures simple density. Photoelectric device, simply measures and
computes how much of a known amount of light is reflected from - or
transmitted through an object. Works on reflectance
Device Profile Determines what colours a device is capable of producing - also known
as profiling or characterization. Only accurate if device is working as
designed.
DHCP Dynamic Host Config Protocol (similar to BootP)
DIMM Dual In Line Memory Module
Discovery Base operating system
Dithers Non solid image area (half ones on B/W)
DLM Dynamically Loadable Module
DM Drum Module - Drum is anodized Aluminium and is expected to last
approximately 3 million prints (life of product?) requires a breaking of 15
minutes at new install.
DMO-E Developing Markets Operations East (was part of RX)
DMO-W Developing Markets Operations West (was part of ACO)
DMU Drum Maintenance Unit, also known as the Cleaning Unit (CU)
DOS Disk Operating Systems
Dosing Amount of ink which was sent from the ink reservoir to print heads -=
measured in grams.
Dot Spread or Dot
Gain
A measure of the final size of a single ink pixel on media after the trans-
fixing process. (Dots may ‘grow’ depending on paper etc.)
DIS Digital Identification Signal
DMA Direct Memory Access
DMO Developing Markets Operations
DOF Direction Of Feed, paper width sensors
DPI Dots per inch
DRAM Dynamic Random Access Memory
Drooling Small amounts of ink ‘oozing’ out of the Print Head, this may eventually
lead to clogged jets and may stain the face plate. If it only happen when
the same SWFA is purging the other head - then 1 PH purges should be
avoided.
Drop Mass The mass of an individual drop of ink that has been ejected by the print
head. Measured during Print Head ‘normalising’ process. Not field mea
-
surable since it requires lab grade scales in zero wind conditions. Drop
mass goes down as a PH ages so compensations / calibration is neces
-
sary.
Drop Mass Param-
eters
Measures the sensitivity of drop mass and drop position to voltage, in
preparation for running “Drop mass reset”
Drum Ghosting Looks somewhat like ink stains.
