| − | uniPHARM uses Lexmark laser printers for printing invoices at each picking station in the distribution centre. The most common model is the T650/T652. In the past we also used the T640 and T630 which have all been phased out. Lexmark colour laser and black only laser printers are present in the office areas. While there is no restriction on the use of other brands of laser printers (HP for example) it is a best practice to keep the number of brands as close to 1 as possible so that users don't have to adjust to 10 different print drivers. The T650 lasers at each of the picking stations is connected to the HP print server box with a parallel cable. When purchasing replacement invoice printers, the parallel port must also be purchased as new black only laser printers don't come with a built in port. This of course wouldn't be a problem if we could just network attach all the picking station printers. Also keep in mind that the T650s that print invoices at the picking stations are all using their factory defaults because they are not network attached. All they need is to be plugged into the HP print server box with a parallel cable and powered on. If the Lexmark still does not print an invoice then power cycle the HP print server box at the picking station. If that still doesn't work then check the network cable. If the green lights on the HP print server box are not blinking rapidly then there is no valid network connection. |

Distribution Centre Printers
uniPHARM uses Lexmark laser printers for printing invoices at each picking station (warehouse zone) in the Distribution Centre. The current models are the MS521 and T652, which replaced the previous T640s and T630s (some still remain). While there is no restriction on the use of other brands of laser printers (HP for example) it is a best practice to keep the number of brands as close to 1 as possible so that users don't have to adjust to 10 different print drivers. The laser printer at each of the picking stations is connected to the HP JetDirect print servers with a parallel cable, but these are being transitioned to Ethernet connectivity. Keep in mind that the JetDirect-connected printers are not visible on the network and therefore are not "fully configured". The advantage to this is that they can be interchanged easily e.g. with printers in other zones, but this method is being retired in favor of fully networked printers.
The Lexmark printers at the picking stations are not setup as shared network printers from a Windows print server. The HP boxes are configured as TCPIP printers on the Lucy Jetforms server, but they are not shared so that users can print to them.
Office Laser Printers
Lexmark printers are also used for departmental/workgroup printing. The current model is the MS417. These are shared through Windows.
Consumables
Replacing the consumables should be evidence based, the print quality or page count should be used to determine if the consumable actually needs to be changed. Resetting the maintenance counter is sometimes preferred as the consumable being low may be inaccurate.
Troubleshooting
Invoices not printing
- If the Lexmark still does not print an invoice then power cycle the HP print server box at the picking station.
- If that still doesn't work then check the network cable (of the print server). If the green lights on the HP print server box are not blinking rapidly then there is no valid network connection.
- There are spare JetDirect servers in the IT Lab (cage), but these are virtually unconfigurable (require XP).
Bad print quality
- Try another toner cartridge. Regardless of toner level, sometimes a replacement can improve/fix image quality. This is because the fuser is built into the toner cartridge for some of these high-volume workgroup printers, and a dirty fuser causes bad print quality
Maintenance warning (fuser)
This is more than likely referring to the fuser and is set to a fixed page counter. There are some tips to keep in mind:
- The printer can still function once this message is bypassed.
- The print quality may be fine despite this message. It is only a recommendation that is triggered by the page count.
- The maintenance counter can be reset.
- If you need to install a new fuser into the LP05 printer in accounting (C748 model) and the printer refuses to see a brand new fuser as a brand new fuser, reboot the printer while holding down the 2 and the 6 buttons on the front panel. The printer will boot into a special configuration menu where you have to reset the page counter on the new fuser. I suppose you could do this same trick when that printer prompts for a new fuser because that printer eats consumables like the fat Austrian kid on the Simpsons eats chocolate.
- To reset the T650/52 d/dn maintenance counter turn the power off, hold the check mark and the right arrow while turning on and wait for the 128mb to flash then wait for the config menu.Reset the maintenance clock from there.
Paper jam
Specifically on the Lexmark printers, paper jam error messages can indicate a worn roller, so this is the first thing to check (assuming that any actual paper jam has been ruled out). To service, you can remove the roller assembly, remove each "wheel", or try to remove the rubber roller in-place (be careful, it's fragile). A quick test as per Lexmark docs is to turn the rubber inside out. If this is the case, it should start to pick up paper again, but replacement rollers should be purchased.
