We use 10 Brother HL-5170DN network-connected printers. The printers come standard with 32MB memory.
Complex images are frequently only partially printed (or not printed at all). It was suggested that we upgrade the memory in the printers to cope with these images.
We have purchased 128MB upgrades, bringing the total memory in the printers to 160MB. The printers do report 160MB as being installed.
The printer includes a configuration option called ‘Page Protect’. This is set to the default of ‘Auto’. Other options include Letter, Legal and A4. Selecting A4 instead of Auto for this option results in the same problem described below.
The only other printer setting that sounds memory related is Input Buffer. The default is ‘3’. I’ve tried setting it to the maximum of ‘15’. There is no indication of the unit of measure for ‘3’ and ‘15’. The problem persists.
Both PCL (5e) and PostScript 3 printer drivers are provided by Brother.
In the PCL printer driver, there is an option under Advanced settings called Printer Memory. This is a drop-down list with a maximum value of 36MB. I have set it to the maximum value – the problem persists.
In the PostScript printer driver there is an option under Advanced Settings, Font Substitution Table, called Available PostScript memory. This defaults to 5029KB.
There is no mention in any of the Brother documentation about this value. Our problem doesn’t strike me as being ‘font substitution table’ related.
PROBLEM: Print jobs containing complex images sent to the printer cause the status light to flash (as if the printer were processing the job) but without generating any printout, the status light returns to normal (solid green).
Can anyone offer insight into what might actually fix our problem? Have we wasted a fair bit of money to buy upgrades that are not going to fix our problems?
