![]() With Diskeeper Professional, optimization is proactive, continuous and seamless.įor IT professionals who need to deploy Diskeeper across multiple PCs, the Diskeeper Administrator console allows for seamless network deployment – no reboot required. InvisiTasking monitors volumes for files that are impacting performance and deploys the Instant Defrag™ engine to consolidate the few remaining fragments on HDDs (SSDs excluded) that were not eliminated by IntelliWrite, if any. InvisiTasking monitors resource consumption on a Windows system (disk, memory, network and CPU usage) and uses only resources that are otherwise idle, so Diskeeper runs invisibly with no intrusion on system resources. Interestingly sending a print job from my iPad via AirPrint wakes up the printer without any problems!įor LAN print jobs I first have to switch the printer off and on again befor I can print.Diskeeper’s intelligent resource monitoring, InvisiTasking ®, ensures all optimization occurs without hampering system resources, so servers can operate at full production while Diskeeper runs in the background. ![]() Even pressing the power button so that the display is on and the button constantly glows changes nothing: Windows can't print and shows the printer as "offline". When the printer goes into sleep mode (which obviously can't be deactivated in the settings) the power button is blinking as it should do - but no print job via LAN can wake up the printer. Right now I have version 20180318 installed. I have exactly the same problem and tried already the last three firmware versions. Never probably isn't required, but I used it on mine since I have it available. Set it as low as you can and reset it to your previous values once you seen it's cleared up. The layout may be different on the M402 series, but it's probably under ECOsmart console in System. You can do this through the HP EWS as well. 2ndary service access has changed (changes with every model or control panel, generally), but you don't need it I tried because I know how and thought it would help. If the changes are major let me know so I can try one in Staples (or a similar store) and see how much has changed. While I prefer the color LCD, I understand the aspect about the 2 line LCD being tried and true. ![]() That being said, I also don't know with 100% certainty since I usually see the color LCD printers nowadays (the front USB port upgrade and better control panel are worth the minor price bump if there's an option). This is a 2 line LCD model, so I suspect it's very, very similar to the M401n setup. ![]() I have also checked 2ndary service and did not find any error codes to work with so it's an open ended problem to try and fix. If it can't be reliably fixed or it's an expensive issue to fix I'm seriously considering buying a new printer at this point. This issue is getting tiring and I need a practical solution. It appears to have been known about since the 2015 Smart Install firmware, but has never been reliably fixed with new firmware. I think the firmware is set to allow downgrades so that may be an option since I archived the 2016022 firmware file (I like to keep one previous firmware revision on hand in case I ever need to downgrade), but that has unpatched security issues on network installations. Since the firmware on the printer is is up to date (20171205/built on 12/15/17), this issue is being caused by something else or something HP COULD fix in firmware but clearly does not care about. The sleep issue managed to stay back for a while, but it has come back again. Once it gets to this point, there's not much I can do to kick it out and get it back online.Īt one point I also had Tray 1 sensor issues and similar sleep issue, but this was corrected with new firmware along with the bad tray 1 sensor. Along with these 2 issues the fastest way to determine if this is the problem is pressing one of the buttons on the control panel.Įven if I press a button on the control panel I usually can't get the printer out of this state without power cycling it. This can usually be caught because the printer doesn't turn off within 8 hours on its own in this state. Since I hook much printer up over USB, I also know it shows up as offline in this state and it does not wake up despite being a wake event. When the printer goes to sleep for an extended amount of time, it has a tendency to stay in sleep mode and requires a power cycle to get it out of this mode. As of late, my HP M401n has been having issues in sleep mode.
