The following manual corrections should be noted: 1. The calculation for Servo Board velocity checks on page 3-34 is wrong, use: 80 CPS - 1040 microseconds LCK to LCK 120 CPS - 694 microseconds LCK to LCK 160 CPS - 520 microseconds LCK to LCK 2. The Preventive Maintenance section on page 3-35 indicates the lead screw should be lubricated. This is wrong, the lead screw should not be lubricated but should be wiped with a dry rag. 3. Figure 3-21, page 3-33 shows 3V peak to peak, this should be 5V peak to peak. The text is correct. The centerline should be 4.6V instead of 5.0V, the text in step 8 is also incorrect. 4. Figure 3-22, page 3-35 has the functions of pots R40 & R25 reversed. These pots may interact, recheck if an adjustment is made. 5. The wrong type of indicator lamp is specified on page 4-37 - is GE86 - should be GE85. Also change item 15 on page 4-38 to PH24/30, MFG # 527840, MM348030. If the GE86 lamp is used it will melt the lens. *** AVAILABLE TRAINING *** Training is included in the Basic Four BBIII/IV Basic School. Video Course # V-108-O Data Royal Adj. Proc.

It will also display the status bytes returned by the printer on the control-task VDT, assisting diagnosis of certain problems. The VDT port to be used must, of course, be switched to the appropriate baud-rate on the VDT controller. 0005 REM "DROYAL...BASIC VDT-PORT PRINTER EXERCISOR 0010 BEGIN 0015 PRINT'CS' 0020 OPEN (1)"T1" 0025 LET C$="" 0030 LET A$=$012020$ 0040 WRITE RECORD(1)A$ 0050 GOSUB 0200 0060 FOR T = 1 TO 1000 0070 NEXT T 0080 LET B$=$02$+"HI THERE ! 0123456789 ABCDEFGHIJKLMNOPQRSTUVWXYZ"+$0A0404$ 0090 WRITE RECORD(1)B$ 0100 GOSUB 0200 0110 GOTO 0060 0200 READ RECORD(1,SIZ=7)C$ 0205 LET C$=C$(2,6) 0210 PRINT "STATUS = ",HTA(C$(1,2))," MODEL = ",C$(3,2)," REV = ",C$(5,2) 0215 REM "FOR BBII - USE SIZ=6 IN STMNT 0200 & DELETE STMNT 205 0220 RETURN If a BBII system is used, it must be configured for binary functions in order to use the HTA function in program step 0210. The program shows T1 as the VDT port used. This is, of course, optional, and any available configured VDT port can be used. It must be RELEASEd at the terminal in order to be OPENed at the task terminal. The text portion of B$ (the message between quotation marks in statement 0080) is optional. Any printable message (up to 132 characters) can be used. Note that this program sends the optional ETX2 character (HEX 04), suppressing the printer LRC checking. This is done to compensate for the action of the video terminal driver software, which adds a carriage return (C/R) character ($8D$) ahead of the line feed ($0A$) in the data sent to the printer.

The new heads can be of two types (UMI or Nanotronics), which are interchangeable. Both types are similar in appearance and do not resemble the Infomag at all. The new heads require different cables and driver PCBs. Part numbers are shown below. 1. New style head and related parts: MM343510, 399010-001 Print head, Nanotronics MM341510, 903116-001 PCB, head driver, Nanotronics MM347510, 906282-001 Flexible cable, Nanotronics MM344011, 906294-001 Carriage assembly, Universal 2. Old style head and related parts: MM343020, 100327 Print head and cable, Infomag MM341050, 100329 PCB, head driver Infomag NOTE: The Infomag head is used with the new or old style carriage assembly. Order either of the following: MM344010, 100308 Carriage assembly, old style OR: MM344011, 906294-001 Carriage assembly, universal NANOTRONICS PRINT HEAD INSTALLATION The new print head requires a nose clamp to keep the nose in the proper position. Care should be exercised when inserting head into the clamp to prevent undue strain. Nose clamp may have to be adjusted. ORIGINATOR: TIC PRINTER-DATA ROYAL-IPS-7,M3200----------------------FIB005 Pg001 FIB 00006 02/18/85 *** Hinge Replacement on Old Style BFISD 132 Column Printers *** Original Document Name - Tech Talk 4-IV-51 Old style DP 80/120/160 CPS printer cover hinge pins may tend to walk out of the hinge bracket (MM348210) due to aging, a condition which could break the cover. At PM or first service call, check the cover hinge roll pins (MM348220) to ensure a secure fit. If loose or questionabe, replace roll pins with the following (two each required): MM363040 - hinge, cover, bolt and nut ORIGINATOR: J. Rippl PRINTER-DATA ROYAL-IPS-7,M3200----------------------FIB006 Pg001 FIB 00007 01/16/87 *** Symptom & Fix Index *** SYMPTOM: Blows fuses 5 & 6; blows power supplies; servo oscillation 1. Clean the lead screw, the Service Manual indicates the lead screw should be lubricated, this is wrong. The lead screw should be cleaned carefully with a dry rag. 2. The power supply should have a modification which replaces transistors Q20 & Q21 with two large transistors on a separate heat sink. All power supplies from repair should have this modification on them. 3. The servo board should be REV - E or later. This revision cures servo oscillation which may also blow the P/S. 4. The lead screw may be binding, check for proper horizontal alignment. Raise the printer frame and loosen servo motor mounting screws, position leadscrew for minimum drag with the frame elevated. The anti-backlash nut may be causing binds, carefully stretch the spring around the nut to reduce tension then recheck the drag. 5. Check for possible shorts on the power supply. This should be done to power supplies before installing in a printer. To check, meter between the heatsink and the transistor tabs that are connected to the heatsink, there should be no connection. 6. Check for loose servo motor brush holders. The rubber capped extensions on the servo motor should not turn. If loose replace the lead screw assembly. 7. The lead screw should be a teflon coated type (black) to reduce drag (all leadscrews from repair should be this type). 8. Check for loose fuse holders on the power supply, fuses should not spin easily in the clips. 9. There is the potential of a short on the head driver board between Q2 and frame caused by a mounting screw that is too long. This may also cause fault lights or print problems. SYMPTOM: Fails to initialize properly; incorrect margins 1. Perform electronic adjustments on pages 3-33, 3-34 of Service Manual BFC 8012A. See FIB 1 for manual corrections. 2. Possible binding/bent leadscrew. 3. Possible bent or dirty timing disk. 4. Possible defective Tach. Check as follows: Disconnect tach from interconnect board, connect a scope probe to one side of the tach & ground the other side of the tach. Move the carriage smoothly end to end while observing the DC output. The tach should output a smooth DC level proportional to the speed of carriage movement (in the range of 1.5V to 3V). PRINTER-DATA ROYAL-IPS-7,M3200----------------------FIB007 Pg001 SYMPTOM: Error 5s; won't communicate with system 1. Error 5s on serial printers connected to standard speed 13xx cpus can be caused by accessory boards below LARL. 2. Parallel interface only - parallel I/O cable may not be trimmed properly at the connector and may short to the I/O PCB. To correct, remove cable from I/O PCB and trim excess ribbon cable with a sharp knife. SYMPTOM: Missing dots; prints incorrectly 1. Poor connections at the head driver PCB may cause missing dots. The ribbon cable connector pins may not be long enough to make good connection. To fix - remove the standoff from the connector. 2. Vertical dot columns may be dropped if the speed is set too fast. The 160 CPS printers do not check speed at initialization time and can be adjusted too fast and still go into a ready state. 3. Check print coil resistance before replacing head driver PCB. A shorted coil will blow the replacement board. Resistance for the coils on a Ballistics head is 2.8 to 3.1 ohms. 4. Printing upsidedown question marks is an indicator of an old level of CPU BD Proms. See F.I.B titled CPU BOARD PROM SETS for correct levels. SYMPTOM: Paper feed problems 1. Paper drive and tractor motor pulleys with metal inserts are available. These allow higher torquing of the setscrews. Part numbers are: Pulley, tractor drive.........MM345211 Pulley, platen drive..........MM345221 Pulley, paper drive...........MM345231 2. Paper jams may be caused by the fanfold perforations catching on the rear top cover sound damper. Repace with new style damper P/N MM348045. 3. Out of specification paper may be a cause of jams & print quality problems. The following paper specifications should be observed: Paper width: fanfolded and 4 to 14 inches wide Single part forms: may vary from 15 to 25 pounds Multipart forms: up to six parts (original plus five copies) may be used when the original is 12 pound stock, copies are 9 to 12 pound and carbon paper is 7 pound. The combined thickness of the forms should not exceed 0.04 inch. SYMPTOM: Fault lights 1. Serial printers require Data Set Ready - pin 6 to be at a space level (+3V to +25V) to come ready and function on line, in addition Clear To Send - pin 5 must also be high. If pin 6 is not high the printer will turn on the fault light. 2. If the speed is set too fast for the prom set (does not affect 160 PRINTER-DATA ROYAL-IPS-7,M3200----------------------FIB007 Pg002 CPS machines) the fault light will come on at the end of the initialization procedure. The speed check occurs after the carriage has found right margin & left margin, a quick 2" motion of the carriage - right then left followed immediately by a fault light is an indicator of a speed problem. 3. Lock ups with carriage jammed to left or right side may be caused by poor connections at the molex connector for the power on switch. SYMPTOM: Ribbon problems 1. Ribbon drive problems may be cause by a defective ribbon drive IC on the power supply (Z4). This should be a 7426 and is mounted in a pluggable socket. The P/N is YY000149. SYMPTOM: Adjustment problems 1. Check extender cable to interconnect board connections. Some extender cables were manufactured incorrectly. SYMPTOM: Blows fuse F1 1. Check indicator lamps for dislodged filaments. Filaments should be supported by a hanger in the center of the bulb, if dislodged may blow F1. Probable cause is vibration from the top cover closing too hard. ORIGINATOR: N. Jones PRINTER-DATA ROYAL-IPS-7,M3200----------------------FIB007 Pg003
