Physical obstruction such as a jammed ribbon Skewed paper detect error. Since the initial reading upon loading a single sheet paper, the paper has skewed. This is a printhead wire protection feature. Illegal paper positioning. (1) If the paper is loaded using the knob instead of the LOAD/EJECT switch, this error condition will occur. This is a printhead wire protection feature. (2) PE sensor may have failed or is not connected. CPU error. An undefined op-code was detected. Error codes 11 and 12 are usually caused by new operators who are un-familiar with the machine. Both of these errors are corrected by turning the printer off, taking out the paper and turning the printer back on. Both features were added to ensure proper paper handling and prevent paper jams, which can result in printhead failures. Incorrect jumper settings on the ROMA board may cause errors 10 or 20. The correct settings are documented in the Service Manual (page A-54, figure A-52) and on TIB LQ2550-005. Enors 0,2, 3, 10, and 20 may require a repair, adjustment or replacement.

LQ - 2550 Error Codes 11 and 12
Date: 4/11/90 Page: 1 of 1
There are two new error codes which can occur in printers with ROM version 022287 or higher. They are error 11 and error 12. Error 11 indicates that the paper is not straight. Error 12 indicates that the paper was loaded using the platen knob instead of the LOAD/EJECT button. When these errors occur, the printer stops, the audible alarm sounds, and one of these two error messages will appear on the front panel. The solution to both of these errors is the same. Follow the steps below: 1. Turn the printer off. 2. Remove the paper. (Use the platen knob if necessary.) 3. Turn the printer back on. 4. Load the paper using the LOAD/EJECT button as described in the manual. OR 4. If you are using a sheet feeder, begin printing again. The printer automatically loads the paper. NOTE: Use the platen knob only for removing jammed paper. Never use it when you are loading paper. Use the LOAD/EJECT button for loading the paper.

CENTRONICS PARALLEL REQUIREMENTS TO ELIMINATE RANDOM
Date: 7/24/89 Page: 1 of 1
The self test can be run in draft mode or Letter Quality mode, depending on which button is held down as the printer is turned on. With the color ribbon cartridge installed, the self test prints in seven colors (black, magenta, cyan, violet, yellow, red, and green). Some colors require two passes, such as yellow and blue combined to make green. When a black ribbon is installed in the LQ-2550 and the self test is run, some lines of the self test are printed in double-strike mode. The printer is making the double passes for the color test, leaving a light and dark appearance to the printout. The self test cannot detect whether a black or color ribbon is installed before printing is executed. The self test can be performed using paper that is at least 8 - 1/2 inches wide, but wide carriage paper is recommended. To perform the self test, follow the instructions below: 1. The power cable is connected to a properly grounded electrical outlet. 2. The printer is turned off and the ribbon is installed. 3. While holding down the LINE FEED button (draft mode) or the FORM FEED button (Letter Quality mode), turn on the printer. The printer will beep three times and the POWER and PAPER OUT lights will turn on, if paper is not installed in the printer, 4. Press the PAPER SELECT button until the type of paper desired is selected. 5. Adjust the tractors or the paper guides to accommodate the size of the paper being using. 6. Press the LOAD/EJECT button once, to automatically load the paper. 7. Press the ON LINE button, to start the self test. 8. A list of the printers current settings is printed first, followed by a series of characters. The self test continues until the paper runs out or until the printer is reset. 9. Press the LOAD/EJECT button, to eject the paper, and turn the printer

10. After the printer is turned off, always wait at least 5 seconds before turning it back on.

SUBJECT: CENTRONICS PARALLEL REQUIREMENTS TO ELIMINATE RANDOM CHARACTERS USING THE LQ-2500 AND LQ-2550
The purpose of the bulletin is to resolve the problem of random characters generated by the LQ-2500 and the LQ-2550. We have received numerous reports from the field regarding this problem. After intensive testing, the problem was isolated to improper Centronics parallel cables. The types of problems encountered were:
Unsuitable shielding - some cable manufactures neglect The cables to include the twisted pair grounds. without proper shielding allow electronic fields to affect the data transfer, thus causing extraneous characters. Shielded cables encase the data lines to protect against external noise. Unacceptable use of parallel communications - The recommended length of a parallel cable is 6 to 10 feet long. When a parallel cable is longer than 10 feet, the flow may become inconsistent causing random For data transfer over characters to be printed. 10 feet in length serial communications is recommended.
If the two issues noted above are corrected, the majority of the problems regarding random characters should be eliminated. Proper shielding should always be verified before any other work is initiated. Many of the older inexpensive cables were manufactured without shielding to help keep production costs down. The length of a Centronic parallel cable should be kept to a maximum of 10 feet for optimum performance. For data transmission over 10 feet in length serial communications is recommended.

Sound intensity is measured in units called Bels (named after Alexander Graham Bell,) or more commonly in tenths of this fundamental unit: decibels. In making noise measurements a weighting network is applied in an attempt to match the frequency response of the instrument to that of the human ear. The most common is the A weighting network, with resulting measurements expressed in dB(A). The following is a list of current products noise levels tested in accordance with standards set by the International Standards Organization (ISO). The acoustic noise levels for the 9 pin printers are averages while printing in Near Letter Quality (NLQ) mode using continuous paper and are not guaranteed figures. The acoustic noise levels for the 24 pin printers are averages while printing in Letter Quality (LQ) mode using continuous paper and are not guaranteed figures. The acoustic noise levels for the laser printers are averages while using single sheet paper and are not guaranteed figures.
