Maintenance Overview
Printronix P7000 Printers
P7000 printers are the latest Printronix line matrix printers to feature PSA3TM (Printronix System Architecture, third generation). This innovative printer architecture puts all data and printer control electronics on the PSA3 controller board. Up to 32 MB of flash memory on this board permits rapid access to stored printer control languages (emulations) and very fast processing of print data. A variable-speed shuttle and micro-step paper feed control enable P7000 printers to print a wide range of horizontal and vertical dot densities, making these printers ideal for high-volume print jobs. The controller board, card cage, and some parts of the ribbon drive system in P7000 printers are new designs and are not electrically or mechanically compatible with earlier Printronix line matrix printers. (For maintenance information about earlier Printronix printers, see page 453.) The principal differences among the various P7000 models are the number of hammers on the hammer bank, whether the printer is mounted on a pedestal or housed in a floor cabinet, and the maximum possible print speed. In this manual, all items described apply to all models except where noted. (See Table 1 on page 19.) Although technically sophisticated, a P7000 printer is easy to use. The mechanical controls that the operator can adjust are colored blue for quick identification. The operator can select every printer function either at the printer control panel or by sending control codes to the printer in the data stream from the host computer. For added security--and to protect special printer configurations--the operator can program which key combination locks and unlocks the ENTER key on the control panel.
Optional Features Enhance Graphics
The PGL and VGL Printronix emulations, bundled together as IGP , are easy to use but highly versatile graphics programming languages that load into the printer's memory and simplify the creation of graphic images. The PSA3 architecture enables multiple emulations and graphic options to be run without additional graphic processors or protocol converters. Depending upon the model, various types of paper stacker are available to handle any throughput requirements. (See "Forms Handling" on page 21.)

Printronix P7000 Printers
Order The Correct Spares
When you replace worn or damaged printer components, make sure you order the correct spares for the model you are servicing. The next section shows you how to identify a P7000 printer.
How To Identify A P7000 Printer
A P7000 printer has a black or gray finish and the PSA3 logo on the printer cover. Every printer also has a model number, which is an alphanumeric code that identifies the printer type, its housing, and its maximum rated print speed. The model number and serial number of the printer are on the identification label next to the input/output ports at the rear of the printer. Figure 1 shows how to inpret a model number.
Housing Code: 0 = Pedestal 2 = Floor Cabinet Printronix Line Matrix Printer P7000 Printer

H = H-Series printer ZT = Zero Tear Pedestal (option)
Speed Rating: 03 = 300 lines per minute (lpm) 05 = 500 lpm 06 = 600 lpm 08 = 800 lpm 10 = 1000 lpm 15 = 1500 lpm 20 = 2000 lpm
Figure 1. How to Interpret a Model Number
Table 1 lists the models in the P7000 series. Remember that the speeds listed are the highest attainable under controlled test conditions. The speed of printing for "real world" print jobs is affected by the interaction of many variables and varies from print job to print job. For more information, see "Printing Rates" on page 294.

H-Series Printers
H-Series models print the ideogrammic symbols used in China, Hong Kong, South Korea, and Taiwan. (See Table 2.) These Kanji/Hanzi/Hangul printers are indicated by the letter H in the model number suffix. (See Figure 1 and Table 1.) H-Series printers have specially designed platens and unique shuttle assemblies which are not interchangeable with any other Printronix printers. Table 2.

Zero Tear Pedestal (ZTP) Printers
Zero Tear Pedestal (ZTP) printers are pedestal models equipped with special hardware and software that permits them to print small jobs or single sheets without losing a sheet between print jobs. The printer automatically presents the current print line to a tear bar when it finishes printing and presents the perforation of the last form printed to the tear bar. When it receives more data from the host computer, the printer pulls the form down to the print station and resumes printing. ZTP printers are covered in Appendix E (see page 417).
Printer Configuration Code
Every printer also has a configuration code which specifies the printer's cabinet type, controller board revision level, V8 ASIC revision level, and MECA ASIC revision level. The configuration code is included in the configuration printout. Figure 2 shows how to interpret the printer's configuration code.

Pedestal Models
Pedestal models provide access to printed forms from the top cover with a tear-at-perforation edge for ejected forms or a paper exit at the rear of the top cover. Pedestal printers also have a wireform paper tray attached to the front of the pedestal and a wireform catch basket attached either to the back of the pedestal or to the back of the printer top cover.
Cabinet Models
Cabinet models can be equipped with four kinds of paper stacking device:
·
The fixed paper fence is a wireform divider that separates the source paper stack from the printed output stack, and is used in combination with hanging chains that guide printed forms downward. For improved performance at higher print speeds, the chains are used with a moveable fence called the "passive paper stacker," which can be positioned to match the form's length. The front access paper stacker consists of a shelf that holds the input paper and a sliding tray that receives the printed forms. The sliding tray pulls forward, permitting the user to both load and unload paper from the front of the printer. This option is helpful in locations where access to the rear of the printer is limited or impossible. For more demanding applications, an optional power stacker is available. (The power stacker is covered in Appendix D on page 369.)

These devices are summarized in Table 3.

Important Maintenance Notes
Important Maintenance Notes
To ensure the best performance of the printer, remember these maintenance principles when you service it. Failure to observe these guidelines can result in damage to the equipment:
·
Do not adjust the platen gap unless 1) the original shuttle assembly or platen has been replaced with a new or rebuilt unit, or 2) you are instructed to do so in a troubleshooting procedure. Never bend or try to adjust ("tweak") the hammer springs. The hammer springs are precisely aligned and the hammer tips are delicate. Always handle hammer springs by the thick mounting base. Use only the ribbons specified in the User's Manual. Using ribbons not made by Printronix can lead to degraded print quality, expensive damage to the printer, and can void the owner's warranty. Never close the forms thickness lever (platen lever) too tightly. Closing the forms thickness lever too tightly can lead to smeared print, degraded print quality, paper jams, and damage to the platen and shuttle assembly.

Plugging In The Printer
In compliance with international safety standards, a P7000 printer is equipped with a three-pronged electrical plug on the power cord. When this power cord is plugged into a correctly wired AC power outlet, the ground conductor ensures that the printer chassis is at ground (earth) electrical potential.
WARNING
Failure to properly ground the printer can result in electrical shock to the operator. Never use adapter plugs that have no grounding prong. Never remove the grounding prong from the power cable plug. If an extension cord is required, make sure it is a three-wire cable with a properly grounded plug.

Preventive Maintenance
Cleaning The Printer
The printer is designed to require very little maintenance. Aside from normal replenishment of paper and ribbons, the only preventive maintenance necessary is periodic cleaning. Periodic cleaning, especially of the ribbon guides and ribbon path, contributes to increased printer life and reliability, and helps sustain superior print quality. Because operating conditions vary so widely, the user must determine how often to clean the printer. But, since there is no guarantee that the user will clean the printer regularly, you should clean the printer every time you are called to service it. NOTE: A cabinet model printer is illustrated in this chapter, but the cleaning procedures presented here pertain to all models.
WARNING CAUTION
Always disconnect the AC power cord before cleaning the printer. Do not use abrasive cleaners, particularly on the window. Do not drip water into the printer. Damage to the equipment will result. Do not spray directly onto the printer when using spray solutions. Spray a cloth, then apply the dampened cloth to the printer. Do not vacuum circuit boards.
Cleaning The Outside Surfaces
1. Set the printer power switch to O (Off). 2. Disconnect the AC power cord from the printer or the power source. 3. Remove the paper. 4. Remove the ribbon. 5. Dampen a clean, lint-free cloth with water and a mild detergent or window cleaning solution. Make the cloth damp, not wet. Wipe down the outside surfaces of the printer. 6. Dry the outside surfaces with a clean, lint-free cloth. 7. Open the printer cover. 8. Using a soft-bristled, non-metallic brush (such as a toothbrush), brush paper dust and ribbon lint off the tractors, shuttle cover assembly (air shroud), base casting, and ribbon guides. Vacuum up the residue. (Figure 5.) 9. Wipe the splined shaft with a soft cloth.

Cleaning The Shuttle Frame Assembly
1. Remove the shuttle cover assembly (page 209). 2. Remove the shuttle frame assembly (page 241). 3. Remove the paper ironer(s) (page 224).
WARNING
Over time, the upper edge of the paper ironer can become sharp. To avoid cutting yourself, handle the paper ironer on the sides. 4. Moisten a clean, soft cloth with alcohol. Wipe the paper ironer(s) to remove lint, ink, and paper residue. 5. Install the paper ironer(s) (page 224). 6. Remove the hammer bank / ribbon mask cover assembly (page 208).
CAUTION
The ribbon mask is easily bent. When handling and cleaning the ribbon mask be careful not to crease or kink it. 7. Moisten a clean, soft cloth with alcohol. Wipe the hammer bank cover and ribbon mask to remove lint, ink, and paper residue. Clean the holes in the cover strips.
CAUTION
Do not use solvents or liquids to clean the hammer tips. Clean the hammer tips gently--too much pressure can chip them. 8. Using a stiff, non-metallic brush (such as a toothbrush), gently brush the hammer tips to remove lint and ink accumulations. (Figure 6.) Vacuum up any residue.
Hammer Tip
Figure 6. Cleaning the Hammer Tips
CAUTION
The hammer bank contains a strong magnet. To prevent damage to the hammer tips, do not let the hammer bank cover assembly snap into place as the hammer bank magnet attracts it. Any impact of the cover against the hammer bank can break hammer tips. 9. Install the hammer bank / ribbon mask cover assembly (page 208). 10. Install the shuttle frame assembly (page 241). 11. Install the shuttle cover assembly (page 209). 12. Clean the card cage fan assembly, as described in the next section.
