How BDT Sheet Feeders Work |
The information in this document applies to:
WordPerfect® 5.1 for DOS
Problem
Symptoms: The user has the original HP LaserJet with a BDT sheet feeder. The user gets a blank envelope from bin 6 and then two blank standard sheets pulled from bin 1 after sending a print job. The user is on a 3COM 3+ network. Solutions: The BDT sheet feeders work as follows: In its memory, it holds all of the printer's codes and concatenations. It will look at the code that is being sent down, and if it doesn't recognize the code, it assumes it is a printable character and selects a bin. If it then receives another bin selection, e.g., ((3)), followed by text, it will make another bin selection. WordPerfect then sends a form feed to eject the page. The result on the sheet feeder is as follows: It sends a page from the default bin which just sits there. If the customer removes the sheet, the sheet feeder will pull from the selected bin. The form feed causes the sheet to be inserted and ejected from the laser printer. To find out if it is a hardware problem do the following: Set the sheet feeder up for Hex dump. This is done by pressing the Online and Test Select buttons simultaneously. Continue pressing the Test Select button until the letter H appears in the LCD window. Press Online and print from WP. For the BDT MF 830 6 Bin this requires the customer to press the FF and Select buttons simultaneously, use the Home/Output buttons to increment the LCD to the number 40, and then press Select to put it back on line before printing. Pressing Reset+Select will return the printer back to its original mode. For the BDT MF 850 3 Bin, press the Online and F1 buttons simultaneously, press F1 till the LCD reads the number 8, press online, and then print. For the BDT LaserFeeder 890, press the Online+Test Select buttons, press test select till the number 8 appears in the LCD, press online, and then print. The hex dump should start with 1B. This is the escape character. If the first character is anything other than 1B, this is the problem. If it starts off with 00 or 1B 1B, this is valid as well. The null (00) and the escape (1B) are not considered as printable characters and should not cause a bin selection. If it does, BDT says to refer these customers to BDT's technical support line. If you do not understand the part about the hex dump, write an STR and have the customer send the hex dump print in. With all of this information the customer did a hex dump through the sheet feeder. the customer found that the first character was not a 1B but a 6, and the second character was an F. The customer then went into WP, set the port to CON and printed. A 6 F did not exist on the screen. The conclusion was that something outside of WP was sending theASCII characters. The cutomer is now going to search out the problem in a different area. |
