::: Problem :::
I have a customer with a HP 4650DN colour printer that has fading problems on black and white printed text files in PC print mode only.
Example when printing Text only :
When printing 5 text pages from the customers PC runing WinXP the first page on this machine is completely blank. The second page has an outline; the 3rd page has legible grey scale; the 4th page has dark gray scale and the 5th page is readable normal black. The same printed text pages fade from left to right as well.
Now to throw a spanner in the works:
If you do a printout from the keyboard via Menu |Information | Configuration | the black and white configuration page comes out perfect every time, multiples times over.
Now to throw the whole toolbox in the works:
If the customer prints colour graphics from the same PC everything works perfectly fine. The customers I.T. guys have multiple HP 4650Dn machines around their business locations and this is the only machine that is displaying this weird fault. The I.T. have replaced the printer drivers with older and newer drivers on their own an at my request. Still the same fault when printing Text based files.If the customer prints a PDF ,Word or RTF document the printer works perfect. Printing from a totally different PC running windows7 and not WinXP the printer works fine.
:: Testing ::
The customer has install a new black PCU in this machine. I have confirmed it's a new black PCU.
I have plugged a lap and top cross over cable into the problem printer with the lastest PCL6 driver. The first pages I test came out (like a polar-bear in a snow-storm) totally blank. I reconfigured the port an all works perfect as it should. When I flood pinging the machine I cannot send a 65565 packet load to the NIC. The maximum response time using a cross over cable is 999 bytes with a 1ms response. If I try 1000bytes the machine returns with a Time out request. If I get I.T. to flood ping the machine the maximum response is 1492bytes with 44ms response.
The problem only appears when using the Text-based database program on three PC's running WinXP; and only on this printer and not any of the other same model printers.
:: Solutions ::
None.
I supsect replacing a faulty RAM chip or an NIC card issue.
It makes it a tad harder as our company doesn't work on HP brand that often...
