Sample of printing (partial) （↑ Print continues.） ************************ ** SAMPLE PRINT No.3 ** ************************ A---00 9876 12345kg ************************ ** SAMPLE PRINT No.2 ** ************************ 05:09 9876 12345kg ************************ ** SAMPLE PRINT No.
6. Advanced use 4: Parameter List A list of current parameters of the M252A is printed. If a code table is used, code table setting values are also printed. Sample of printing （↑ Print continues.） kg 04:Unit Selection Ach Gross 03:Print Data Bch Gross 02:Print Data Ach 2000/07/01 05:11 01:Date/Time ************************ ** PARAMETER LIST ** ************************ ■ As a parameter list, 100 lines are printed in total (approximately 35cm).
6. Advanced use Over print Print data out of the range set by the connecting indicator or the M252A is identified by this function. There are two types of over print: over status (R) and range over (U/L). Over status (R) If the indicator side causes a LOAD (A/D converter input over), OFL1 (net>99999) or zero abnormality, "R" is added after printed data, and the data is not added to grand totals/sub totals. It is not counted up either.
6. Advanced use Range over (U/L) If the range set under Target Value Ach (Bch) and Range Ach (Bch) is exceeded, the print is added after printed data. If the upper limit is exceeded, "U" is printed, and if the lower limit is exceeded, "L" is printed. (Example) When the target value is set at 100, and the range at 20. Lower Target limit value L print 55.0kgL etc 0 Upper limit ‘U’ print Measurement value > Target value + Range U print 150.
6. Advanced use Delete print Use if you want to delete printed data (when you do not want to add the data to subtotals/grand totals). Only one piece of the last printed data can be deleted. Press [DEL] → [ENT] in the print mode, and the data is deleted.
6. Advanced use Initialization The internal memory of the M252A is completely cleared, and the parameters are restored to their factory default settings. 1. Turn on the power while pressing the [A] key. 2. Since the following is printed, press [ENT]. Cancel --> ESC OK --> ENT ----All data initial---- operating To execute initialization: [ENT] To cancel initialization: [ESC] 3. If the following is printed, initialization is successful.
6. Advanced use Date print Press [DATE] → [ENT] in the print mode, and the current time is printed.

7. Troubleshooting Classification of trouble Find applicable trouble out of the following, and take remedies according to the reference page. If printing still cannot be generated properly, check the ROM version of the M252A body (See page 71) and contact us. The printer does not operate properly. The M252A does not start............................................................................................. P.71 Printing is not generated...............................................................
7. Troubleshooting The printer does not operate properly Trouble 1 The M252A does not start. Cause 1 The M252A is not connected to a power source. Remedy1 Check that the power cord is fixed properly. Cause 2 If the power LED does not light even though the M252A is connected to a power source, the fuse may have blown. Remedy1 Since the fuse has been installed inside the M252A, disassembly is necessary for replacement. Therefore, it should be replaced by UNIPULSE.
7. Troubleshooting Cause 3 The printer is clogged with dust or jammed with paper. Remedy1 Open the push panel, and check the mechanical part of the printer. Remove dust with air or the like. Remedy2 In the case of a paper jam, the printer is locked, so that [Print] and [Feed] cannot be used. It may cause some trouble if you pull the paper fast or backward when you remove the paper. Please pull the paper forward slowly and straight to remove it after stopping the paper feed.
7. Troubleshooting The printer does not function properly Trouble 1 Cause 1 Printed counts are wrong. Counts are stored in battery-required memory. If the power is turned off and on again with the battery exhausted, a problem occurs such that printing is not counted normally. Remedy1 The battery needs to be replaced. Since the battery should be replaced by UNIPULSE, contact your dealer representative. The average life of the battery is approx. 8 years.
7. Troubleshooting Others Trouble 1 Remedy1 Printing has been generated by mistake. The last piece of printed data can be deleted by delete print. For the details, see "Delete print"(page 70). Trouble 2 Cause 1 The target value cannot be set. The setting cannot be made if the total of the absolute value of the target value and the range exceeds 99999. Remedy1 Since the initial value of the range is 99999, the target value cannot be set in a initial state.
7. Troubleshooting Cause 2 In Print- Every, Warning (Buzzer) will sound if number of code in each channel exceeds 32. In this case, Count to first code after GT Print, and print the code. Remedy2 Please operate each channel with 32 code or less. When the GT Print is done, the number of code is reset to 0.
