打印头组件是容纳打印机墨盒的隔间。您的打印机显示“打印头缺失(Missing)或故障”错误，表明打印头出现故障。该问题可能是由于墨水喷嘴堵塞、墨盒脏、内部卡纸等造成的。
如果打印头从墨盒中吸入空气，HP 打印机也可能会显示此错误。本教程介绍HP 打印机(HP printers)上“打印头缺失或故障”错误的故障排除修复。
重新启动(Restart)或恢复出厂设置您的(Factory Reset Your)打印机
重新启动打印机可以解决常见的打印机问题(common printer problems)，也可以将其设置恢复为出厂默认设置。
注意：将 HP 打印机恢复出厂设置不会重置其页数、语言或纸盘大小。
- 关闭打印机并将电源线从墙壁插座上拔下至少 30 秒。
- 将打印机重新连接到电源并打开它。如果您的打印机有“恢复”(Resume)按钮，请在打印机启动时按住该按钮 10-20 秒。
- 当黄色“注意”灯亮起时，松开“恢复”按钮。(Resume)当您的预设重置为出厂默认值时，“注意”和“就绪”指示灯会循环亮起。
如果缺少打印头的错误消息仍然存在，请重新安装打印机的打印头。
重新安装 HP 打印机打印头
(HP printers might malfunction)如果打印头未正确安装在笔架中，HP 打印机可能会出现故障。重新安装打印机的打印头并检查是否可以停止“打印头缺失(Missing)或故障”错误。在重新安装或重新对齐打印头之前，请关闭打印机并拔掉电源线。
打开打印机墨盒检修门，提起笔架上的闩锁，然后轻轻地将打印头拉出一半。返回笔架闩锁以牢固锁定打印头。
如果重新安装打印头无法解决“打印头缺失(Missing)或故障”错误，请尝试以下故障排除步骤。
检查是否卡纸
(Paper)打印机内部卡纸可能会导致无法检测到打印头。关闭打印机，断开电源线，然后检查墨水或碳粉盒检修区域是否有卡纸。
检查笔架路径和其他区域，并清除打印机内的纸张碎片。关闭墨盒检修门，然后重新连接打印机的电源线。
清洁或更换墨盒(Ink Cartridges)
(Dirt)打印机墨盒上的(printer’s ink cartridges)污垢、碎片或墨水残留物也可能引发打印错误。从打印头上取出墨盒并擦去积聚的污垢或碎屑。HP 建议使用蘸有蒸馏水的干净、干燥、不起毛的布清洁墨盒。
您还应该轻轻擦去打印头和笔架上铜色电触点上积聚的墨水。将墨盒卡入其颜色编码的插槽中，关闭墨盒检修区域，然后打开打印机。
触摸墨水喷嘴或清洁电气触点可能会导致打印质量问题(print quality issues)和电气故障。同样(Likewise)，将墨盒或打印头长时间留在打印机外（超过 30 分钟）可能会损坏墨盒和打印机。
快速（但小心）清洁墨盒和打印头并立即更换。请参阅此 HP 支持教程，(this HP Support tutorial)了解有关清洁打印机墨盒和打印头的更多信息。
某些HP 喷墨(HP Inkjet)打印机的控制面板中具有“清洁打印头”功能。根据您的打印机型号，您可以在控制面板的“工具(Tools)”、“维护”或“打印机服务”部分找到清洁选项。(Services)有关访问或使用其清洁工具的说明，请参阅打印机手册。
如果打印头问题仍然存在，请检查(Check)打印机和墨盒之间的连接问题。确保墨盒连接正确，并且其塑料卡舌与打印头对齐。
此外，检查墨盒的芯片并确保其固定正确且状况良好。您可能需要更换整个墨盒包，尤其是在使用非 HP 墨盒时。
更新打印机的固件
将打印机固件更新到最新版本有时可以解决打印头错误和其他打印故障(printhead errors and other printing malfunctions)。您可以通过 HP 网站或HP Smart应用程序更新打印机的固件。
从HP 网站(HP Website)更新您的打印机
- 访问 HP 网站的软件和驱动程序下载页面(Software and Driver Download page)并选择打印机。
- 在对话框中输入您的 HP 打印机型号或名称，然后选择提交(Submit)。
- 展开“固件”类别并选择最新固件文件旁边的
下载。(Download)
- 解压缩文件并按照随附的PDF文档中的说明安装固件更新。
安装固件更新后重新启动计算机和打印机。在固件更新过程中保持打印机电源打开。更新固件时发生电源故障或转动打印机可能会对打印机造成不可逆转的损坏。
通过HP Smart更新您的打印机(Printer)
更新打印机固件的步骤可能会有所不同，具体取决于HP Smart应用程序版本和您的打印机型号。
在HP Smart(HP Smart)应用主屏幕上选择您的打印机，然后选择高级设置(Advanced Settings)或打印机主页(Printer Home Page)( EWS )。接下来，前往Tools/Web 服务” (Services) > Printer Update”并选择“立即检查”(Check)。
HP Smart(HP Smart)应用程序将自动下载任何可用的固件更新并将其安装到您的打印机上。
您还可以从打印机的控制面板安装固件更新。此HP 客户支持文档(HP Customer Support document)重点介绍了在 HP 打印机上安装固件或驱动程序更新的不同方法。
修复 HP 打印头故障错误
如果打印头缺失错误仍然存在，请联系 HP 支持(Contact HP Support)或当地服务中心。如果您的打印机有缺陷且在保修期内，您将获得新的打印头或替换打印机。使用HP 的产品保修检查工具(HP’s Product Warrant Check tool)来验证打印机的保修或服务状态。
否则，如果您的产品已过保修期，HP 将为您的打印机提供收费服务或维修。
How to Fix Missing or Failed Printhead Error on HP Printers
The printheаd assembly is the cоmpartment that houseѕ your printer’s ink cartridges. Yoυr printer displays the “Missing or Faіled Printhead” errоr to signаl a malfunctioning printhead. The issue could be due to clogged ink nozzles, dirty ink cartridges, internal paper jams, and more.
HP printers may also display this error if the printhead pulls air from ink cartridges. This tutorial covers troubleshooting fixes for the “Missing or Failed Printhead” error on HP printers.
Restart or Factory Reset Your Printer
Rebooting your printer will fix common printer problems, so will restoring its settings to factory default.
Note: Factory resetting your HP printer won’t reset its page count, language, or tray size.
- Turn off your printer and unplug its power cord from the wall outlet for at least 30 seconds.
- Reconnect your printer to its power source and turn it on. If your printer has a Resume button, press and hold it for 10-20 seconds while your printer boots.
- Release the Resume button when the yellow “Attention” light comes on. The “Attention” and “Ready” lights cycle while your preset resets to factory default.
Reseat your printer’s printhead if the missing printhead error message persists.
Reseat Your HP Printer Printhead
HP printers might malfunction if the printhead isn’t seated correctly in the carriage. Reseat your printer’s printhead and check if that stops the “Missing or Failed Printhead” error. Turn off your printer and unplug its power cable before reseating or realigning the printhead.
Open your printer’s cartridge access door, lift the latch on the carriage, and gently pull the printhead halfway out. Return the carriage latch to lock the printhead firmly.
Try the troubleshooting steps below if reseating the printhead doesn’t resolve the “Missing or Failed Printhead” error.
Check for Paper Jam
Paper jams inside your printer can prevent the detection of the printhead. Turn off your printer, disconnect its power cable, and check the ink or toner cartridge access area for jammed paper.
Examine the carriage path and other areas and remove torn pieces of paper inside your printer. Close the cartridge access door, and reconnect your printer’s power cable.
Clean or Replace the Ink Cartridges
Dirt, debris, or ink residue on your printer’s ink cartridges can also trigger printing errors. Remove your ink cartridges from the printhead and wipe off accumulated dirt or debris. HP recommends cleaning ink cartridges using a clean, dry, and lint-free cloth damped in distilled water.
You should also gently wipe accumulated ink off the copper-colored electrical contacts on the printhead and carriage. Snap the ink cartridges into their color-coded slots, close the cartridge access area, and turn on your printer.
Touching the ink nozzles or cleaning past the electrical contacts can cause print quality issues and electrical failures. Likewise, leaving your ink cartridges or printhead outside the printer for an extended period (over 30 minutes) can damage the cartridges and printer.
Clean the ink cartridges and printhead quickly (but carefully) and replace them immediately. Refer to this HP Support tutorial for more information on cleaning your printer’s ink cartridges and printhead.
Some HP Inkjet printers have a “Clean Printhead” function in their control panels. Depending on your printer model, you’ll find the cleaning option in the “Tools,” “Maintenance,” or “Printer Services” section of the control panel. Refer to your printer’s manual for instructions on accessing or using its cleaning tool.
Check for connectivity issues between the printer and cartridges if the printhead problem persists. Ensure the ink cartridges are connected correctly, and their plastic tabs align with the printhead.
Additionally, inspect the cartridge’s chip and ensure it’s properly fixed and in good condition. You might have to replace the entire cartridge pack, especially if using non-HP cartridges.
Update the Printer’s Firmware
Updating your printer’s firmware to the latest version sometimes resolves printhead errors and other printing malfunctions. You can update your printer’s firmware through HP’s website or the HP Smart app.
Update Your Printer from HP Website
- Visit HP’s website’s Software and Driver Download page and select Printer.
- Enter your HP printer model number or name in the dialog box and select Submit.
- Expand the “Firmware” category and select Download next to the latest firmware file.
- Unzip the file and follow the instructions in the attached PDF document to install the firmware update.
Restart your computer and printer after installing the firmware update. Keep your printer powered on during the firmware update process. Power failure or turning your printer while updating its firmware can irreversibly damage the printer.
Update Your Printer via the HP Smart
The steps for updating your printer’s firmware may vary depending on the HP Smart app version and your printer model.
Select your printer on the HP Smart app home screen and select Advanced Settings or Printer Home Page (EWS). Next, head to Tools/Web Services > Printer Update(s) and select Check Now.
The HP Smart app will automatically download and install any available firmware update onto your printer.
You can also install firmware updates from your printer’s control panel. This HP Customer Support document highlights different ways to install firmware or driver updates on your HP printer.
Fix HP Failed Printhead Error
Contact HP Support or a local service center if the printhead missing error persists. You’ll get a new printhead or replacement printer if your printer is defective and under warranty. Use HP’s Product Warrant Check tool to verify your printer’s warranty or service status.
Otherwise, HP will service or repair your printer for a fee if you have an out-of-warranty product.
