Introduction
The PRU0901 and PRU1201 are high-speed belt printers that can be con~
nected to DPS Extended and DPS 8 systems by using a peripheral device
serial interface (pDSI). The PRU0901/1201 can produce clear printed charac-
ters at nominal speeds of900 and 1200 lines per minute (lpm) respectively
with a 64-character print belt. To providefor future system needs, the
PRU0901 can be upgraded on site (via PRK0901 )to a PRU1201.
Features
Introduction
Designedto help meet current and future needs of the data processing user,
the PRU090111201 feature:
• Excellent print quality
• High throughput and reliability
• Operator efficiency
• Improved system availability
Excellent Print Quality
Smearless printing and precise alignment of printed characters are achieved
through the use of a print belt that is well suited forjobs demanding high-
quality appearance.
Each character on the print belt is mounted on a flexible ~~finge!'." During
printing, the belt passes continuously at high speed in front of the print ham-
mers. When a character is struck, the flexibility of the finger causes the
character to beimmobilized at the moment of impact. This elimination of drag
helps produce smearless, ghost-free, printed copy.
Depending upon the paper stock being used, an original and up to five carbon
copies can be produced.
1-1 CW99-00

Introduction
High Throughput and Reliability
The rated print speeds of the PRU0901/1201 are 900 and 1200 lpm respec-
tively for continuous single-spaced line operation with a 64-character set. The
printers feature paper skip speed of29 or 44 inches per second and software-
controlled
vertical line spacing of6 or 8 lines per inch.
Longer ribbon life ispossible as a result of reduced ribbon drag during the
printing process. Also, the life of the printer itself can be extended by an
Automatic Standby feature that deactivates the operating mechanism of the
device when it is not being used.
Operator Efficiency
Operator efficiency is enhanced by the automatic paper stacker, whichis
included
with the printer; the simplicity of paper loading and ribbon changing;
and the quick and easy exchange of the lightweight, easily accessible belt
cartridges. A special re-inking feature in the ribbon cartridge helps toreduce
ribbonchanges.
Clear alphanumeric error displays are easily visible to the
operator only when active. Improved acoustical design results in quiet and
efficientoperation. An optional static eliminator is available to improve paper
stacking.
IlDprovedSystelD Availability
Softwarecontrol of online error status reporting helps reduce:
• System time required for diagnosis
• Unit time required for oflline repair
• Servicecalls
1-2 CW99-00

Introduction
Print Belts
Two identical print belts are supplied with the printer. The customershould
complete
and return the belt warranty card that accompanies the printer.
Each print belt comes with a lightweight cartridgeto facilitate removal, inter-
change,
and storage. The system is programmedto recognize the beltbeing
usedfrom a code on the belt. (See Appendix B for a list of the available print
belts.)
Ribbons
The printers use a 2-inch-wide, 50-meter-longnylon ribbon having a ribbon
life of 4.5 to 6 million lines.
The ribbon system is composed
of a ribbon cassette assembly, ribbon refill
cartridge,
and ribbon inker. The operator can maximize print ribbon life by
performing Degree I maintenance (Section 4) and by monitoring the condition
of
the ribbon inker's felt wick to ensure the free flow of ink to the transfer
roller. When ribbon replacement is necess8.J.--j', both the ribbon refill cartridge
and the ribbon inker must be replaced. For order information, refer to
Appendix B in this manual; the Honeywell Computer Supplies Catalog, Order
No. BY62; or contact your Honeywell Marketing Representative.

or vice versa. The NORMAL indicatormust be lit to go
into the READY state.
Thispush
button control advances the paperto the top of the

This indicatoris litwhen
the printer is in the READY

fault
or error is corrected. (The printer must be in the
STANDBY state.)
Thispush
button control advances the paperone line. The
printer must be in the STANDBY state.
This indicatordisplays a two-digit hexadecimal code. A display
of 00 indicates that there is no problem; any otherdisplay alerts
theoperatorto operatorcorrectableconditions or printerproblems.
(See Appendix A for errorcodes.) During
test execution the

Function
This switchplaces the printer in the REMOTE state for coma

test programs that reside in the printer.
Thisswitch must be in the OCR positionfor high-qualityprinting
(900 lpm). In all other cases, it should be inthe NORMAL posi-
tion. This switch is not effective on the PRU0901 printer.
This indicator is lit when the ribbonweld is passing in front of
the print station. Printing is temporarily inhibitedwhile this
indicator is lit. (This occurs at 6-minuteintervals during continuous
operation of the printer.)
The printer runs the internal test programs when thisswitch is
in the TEST position and the printer is in the LOCAL state. An
error code is displayed ifa fault isfound.

Function
These levers (see Figure 2-2)permit the operator to unlatch and
open the belt unit. An unlatched condition (errorcode 06)is
notified by a switch.
To remove
the ribbon cassette, this lock (see Figure 2-2) must be
set parallel to the opening in the cassette.
This lever (see Figure 2-2) permits the operator to release the
print belt for removal or to tighten the print belt during installa-
tion. The ribbon cassette must be removedto gain accessto the
lever.
When no paper is present between this bar (see Figure 2-2) and
the paper entry guide, an end of paper condition (errorcode 05)
is notified.
Loosening
the tractor locks (see Figure 2-2)allows the operator
tomove the tractors horizontally in order to change the form
width.
This knob (see Figure 2-2)allows the operator tomove the paper
manually through the printer for line adjustment. The tractor
clutch switch (see Figure 2-4) must be in the declutchedposition.
This screw (see Figure 2-2) permi ts the operator to adjust the
paper horizontally with the tractors locked. This device is pro-
vided
as an option.
The line indicator (see Figure 2-3), used together with the line
adjustment knob, permits the operator to position the first line
tobe printed.
The column indicator (see Figure 2-3) permits the operator to
position
the first column to be printed bymoving both tractors
horizontally or using the horizontalfine adjustment.
This control (see Figure 2-4) regulates the force of the print
hammers. The setting dependson the number ofcopiestobe
printed. The control must be set such that proper print quality is
obtained with the lowestpossible hammer force.
This switch (see Figure 2-4)controls the instant of hammer fir-
ing.
The switch must be set togive equal print density on both
sides of the characters.
This switch (see Figure 2-4) permits the operator to disengage
the tractor drive shaft in order tomove the paper manually
through the machine.

motor operates to accommodate the printer output.
This push button control starts the stacker paper feed motor.
The motor runs for 6 seconds after the button is pressed. It is
used for
