3.1.5 Mainframe Line Printer - IBM 6262 Model 022

The 6262 model 022 is a high speed impact line printer attached to a block multiplexor channel on the mainframe computer located in the Data Center computer room.

It prints on continuous fan folded pin-feed driven forms. The vertical movement of the forms is controlled by the print application software and a FCB (Forms Control Buffer). Text is printed on forms using a print band UCS (Universal Character Set) and a ribbon. The printer speed varies depending upon the print application characteristics. The printer has medium to low density Bar Code capability but it is not currently supported.

Refer to Chapter 6 and Appendix C for additional information on printers.

 

3.1.5.1 Line Printer Forms - IBM 6262 Model 022

  1. Appendix C contains a description of the forms currently available. Forms are assigned a form number by the Data Center’s Operations staff.

  2. The 6262 prints on single-ply, card stock, multiple part, pre-printed, labels, carbon, and NCR (no carbon required) forms. It is capable of producing machine readable input documents for an OCR (Optical Character Reader).

  3. Excluding the DEFAULT form for sysout classes "A" and "E", a form is selected for printing via JCL parameters that specify a sysout class, form number, and FCB. The UCS parameter is also specified if a non-default UCS is desired. These JCL parameters will generate a message on the computer operator console asking for a printer forms mount.

  4. The DEFAULT form (number 1181) is printed on 1 ply 14 7/8" X 11" green bar stock paper at 8 lines per inch (FCB P118), using the default print band (feature #9502). To use the DEFAULT form, specify JCL parameter SYSOUT=n (where n = sysout class "A" or "E" (do not specify form#, FCB, UCS).  

 

3.1.5.2 Line Printer FCB (Forms Control Buffer) - IBM 6262 Model 022

  1. Refer to Appendix C for a list of available FCBs.

  2. FCB controls the vertical movement of forms as they are printed. It controls channel skipping, line spacing, and printing of data at 6 and 8 lines per inch.

  3. Data Center abstract TS007500.RU provides additional guidelines for print applications.

  4. FCBs are created by the Data Center’s Technical Service staff upon request.

  5. An FCB is selected by the JCL FCB parameter. The operating system JES2 (Job Entry Subsystem) default FCB P118 does not require a JCL parameter to select it when printing to sysout classes "A" and "E". FCB P118 prints on a form length of 11 inches at 8 lpi.

 

3.1.5.3 Line Printer UCS Print Band - IBM 6262 Model 022

  1. The printer supports 10 CPI (characters per inch) print bands. The print band feature reflects the UCS (Universal Character Set) capability. The maximum print line length is 132 contiguous characters. The recommended character height is .105". We currently use 079" and .095" print bands.

  2. The print band is operator mounted upon request via the JCL UCS (Universal Character Set) parameter.

  3. The DEFAULT UCS print band (feature #9502, part #6475398) consists of 64 unique characters (alpha/numeric and common special symbols) to support the majority of print applications. It prints a character height of .079 inch. Do not code the JCL UCS parameter to select the default print band.

  4. A TN UCS print band (feature #9507, part #6475410) is available for special print applications. It consists of 128 unique characters (alpha/numeric and many special symbols) for complex print applications. It prints a character height of .095 inch and works best with a FCB that prints at 6 lpi (not 8 lpi). Refer to Chapter 6 for additional information on using the TN print band.

  5. Contact the Data Center Operation’s staff for print band character set support.  

 

3.1.5.4 Line Printer Ribbon - IBM 6262 Model 022

A General Purpose or High Contrast Nylon ribbon will normally be mounted on the printer. The operator will mount the other ribbons as requested per standard operating procedures.

  1. General Purpose - An average quality ribbon used for production print applications.

  2. High Contrast Nylon - A high quality ribbon used for production print applications.

  3. Polyester (Mylar) - A high quality ribbon for Bar Code applications. Bar code printing requires a print band brush and interposer which are maintained by the Data Center.

 

3.1.5.5 Line Printer Speed - IBM 6262 Model 022

Printer speed depends on the UCS print band type, forms design, and FCB usage. The print speed using the DEFAULT UCS print band (feature #9502) is about 1840 lpm (lines per minute). When using the TN UCS print band (feature #9507), the speed is about 1115 lpm.

 

3.1.5.6 Line Printer Forms Specifications

 

 

Minimum

Maximum

Thickness .003 inch (.08 mm) .020 inch (.51 mm)
Number of Parts 1 6 (suggest 4)
Weight 15 lb. (56 gm/sqm) 100 lb. (163 gm/sqm)
Width 3.5 inch (89 mm) 18.5 inch (470 mm)
Length(form layout) 3 inch (76 mm) 14 inch (356 mm)
Length(fold to fold) 6 inch (152 mm) 14 inch (356 mm)


Thickness: The measurement includes the sum of all parts of a form including any carbons. Single-ply forms are .003 inch (15 lb.) or heavier. OCR paper stock should be single-ply bond 20 to 24 lb. for best results. Card stock should be about .007 inch.

Number of parts: 5/6 part forms may result in poor quality. Do not use multi-ply forms for OCR printing. For OCR print, use 20-24 lb. (75-90 gm/sqm) OCR bond single-ply.

Width: The measurement includes the pin feed strips on the side. Forms wider than 15.9 inch (405 mm) have limited horizontal venire adjustment. Also the first print position will always be 15.4 inches (392 mm) from RIGHT edge of the paper as forms width increases to maximum dimension. This means the printer is restricted when printing on the left side of the form.

Length: Forms can be as short as 3 inches long if they are packaged to stack at the printer 2-up. That is 6 inches from fold to fold. Forms longer than 14 inches, up to 17 inches, can be accommodated with the printer unit's doors open, if a special option is installed.

3.1.7 Mainframe Page Printer - IBM 3160-1

The IBM 3160 printer is mainframe LAN attached all-points-addressable laser electrophotographic page printer that supports the Intelligent Printer Data Stream (IPDS) for Advanced Function Printing (AFP). The 3160 printer is addressable only through the JES destination parameter with the address of DCPRT7.

  1. Prints in black, on single part, cut-sheet paper, pre-printed forms, in either simplex or duplex modes.

  4. Paper Quality: Use only high-quality xerographic paper for optimum paper and printer performance and print quality. The use of other paper types may cause degraded performance such as seen with paper curling and poor toner bonding that results in loss of printer availability and increased service costs.

  5. Maximum print speed of 60 impressions per minute in simplex mode or 30 impressions per minute in duplex mode. The rate is also affected by paper weight, text type, and graphics printed.

  6. Font sizes range from 4 to 72 points at 240 PEL.

  7. Prints 1-Up and multiple-up formats, in either landscape or portrait presentations.

  8. Although the printer is capable of printing to the edge of the paper, to be assured of quality results, do not print text within .1 inch of the paper edge, punch holes, or paper perforations.   And images should remain at least .5 inch from the paper edge, punched holes, and paper perforations.
