HP 750c Service Manual - Page 205

D MIO 5.0 support: The plotter officially only supports MIO cards which provide MIO 6.0 functionalities. With MIO cards that do not provide MIO 6.0, the plotter reports a System Error 040601. But if it is an MIO 5.1 HP JetDirect card, this error is cleared after pressing Enter". The plotter will work normally, but it will not be able to use any PML functionality. This is not a problem for HP JetDirect cards, as long as they have FLASH to be reĆprogrammed. The MIO 6.0 version A.03.15 works perfectly. Because the plotter does not officially support MIO 5.0, problems could be the same with 3rd party cards. D JetDirect EX family: When the plotter uses a JetDirect EX, JetAdmin ( Windows /Unix ) always report Status: online" even if the Cover is Open (same result with Lever Up and Out of Media ). If you continue asking the printer status, the error event ( e.g. Cover Open ) is seen once every 10 times. D Fixed corner case problems in HPĆGL / HPĆGL2 instructions. Dashed lines printed with LTO are printed continuously. D PostScript: When printing in an area which is located between two white areas (e.g it is nonĆprinted areas), some swaths can be lost. This could occur, for example, when printing a line. The result would be a lighter color than expected. Or, if printing two separated lines with the same color, one of them could be lighter than the other. The occurrence of the problem depends on the position on the page and on the width of the printed areas. This means that you can obtain the correct color by moving the line. There is a workaround: If printing in color, the problem never appears if the line width is 5.5 mm(0.22 inches) or more. If printing in monochrome, the line should be 6.8 mm (0.27 inches) or more in width to be sure that no swaths are lost. D PostScript: When canceling a Postscript print, the Front Panel is reports a Ready" message when in fact it is canceling. D DISPLAY DATA doesn't not work after sending HPĆGL2 files. The files received afterwards are printed. D Plotter hangs when sending files with many bitmap fonts. D Printing in small margins, after canceling one file, it can be printed attached with the following file. Firmware A.02.05 Release uniquely used in the Japanese Market. D Corrects some localization errors D Smart Area fill problem (in some cases, one pass not done).
