HP Officejet Scanner
Posted on 2013-11-22
Hi, We have several HP Officejet 4620 multifunction devices on our Windows SBS domain with windows 7 clients. Some are on the WLAN and some connected to the local client via USB. All have the latest firmware available from HP installed, and were installed with the latest full featured driver available from the HP website.
Periodically and randomly, any one of them will not be able to scan to the computer due to a failure of communication between the printer and the HP software on the computer, this is always after the printer has gone dark and has been in what I suppose is a sleep mode, usually first thing in the mornings. If the printer is woken up by pressing any one of the buttons on the console, after two or three minutes the communication is restored and scanning to the PC is possible. This happens regardless of whether scanning is initiated on the printer console or in the HP Scan utility on the computer.
At first, all of the printers were on the wireless network, not using the USB connection. I thought the issue was most likely related to the wireless connection so I converted some of them to USB and disconnected them from the WLAN. It turns out the connection method does not seem to matter, the issue also occurs via USB.
I double checked that all of the latest software, updates and firmware are installed. The computers themselves do not go to sleep or get turned off at night. The screen goes dark after inactivity, but the PC remains on.
Any suggestions to resolve this? Thanks!
