Brand new hp c310 only prints blank pages. It is connected correctly. Tried powering off unplugging power and usb cables and reconnecting and powering back on no luck. ????? I have seen several similar posts on various boards with no solutions found to solve the problem.

Solution one: Check the ink levels To allow for full use of the cartridges, some printers continue to print even after the cartridges are completely out of ink. Follow these steps to check the ink levels in the Toolbox . The Toolbox is part of the standard printer software. Depending on the version of Toolbox on your computer, the appearance of the Toolbox features might vary.
NOTE: Ink level warnings and indicators provide estimates for planning purposes only. When an indicator shows low ink levels, consider having a replacement cartridge available to avoid possible printing delays. Print quality deteriorates as cartridges run out of ink.

1. Click Start ( ), click All Programs , click the HP folder, and then click the icon for your HP printer ( ). The printer software opens.
2. In the printer software, double-click Estimated Ink Levels . The Toolbox opens.
3. Click the Estimated Ink Levels tab to display the estimated ink level of each cartridge. Figure 1: Estimated ink level indicator Image: Estimated ink level indicator.
4. If the ink level indicators show that a cartridge is low or empty, replace the cartridge.

Hi,

The "Ox18" series errors can be removed by resetting the printer. Unplug the USB cable from the printer, remove the ink cartridges. When the "Insert ink cartridges" message appears unplug the power cord from the printer. Wait 1 minute (at least), then reconnect the power cord and turn on the printer if it didn't come on by itself. Reinsert the ink, close the unit and print a calibration page if prompted to do so. Finally reconnect the USB cable to the printer. If this doesn't work, the unit needs service (or replacement if the service call will cost more than a new printer).

Thank you!!

tion one: Check the power supply Follow these steps to check the power supply to make sure that it is functioning correctly.

1. Turn the product so that you can access the rear side.
2. Unplug the power cord from the back of the product. Figure 1: Unplug the power cord from the back of the product
3. Remove any devices between the product and the power outlet, such as surge suppressors or power strips.
4. Plug the power cord directly into a wall outlet.
5. Print and time a self-test again.

• If the test page prints in 30 seconds or less , the problem relates to the power supply. Replace devices between the product and the power outlet, or leave the product connected directly to the wall outlet.
• If the test page takes significantly longer than 30 seconds to print, continue to the next solution in this document.

Solution two: Check the USB connection

1. Disconnect the USB cable from the back of the HP product. Figure 2: Disconnect the USB cable from the back of the HP product
2. Disconnect the USB cable from the back of the computer.
3. Wait five seconds.
4. Reconnect the USB cable to the back of the product and the computer, according to the following guidelines: The icon on the USB cable ( ) faces up when the cable connects to the product correctly. Connect the small end of the USB cable to the back of the product Connect the other end of the USB cable to the computer
5. After you make sure that the USB cable connects correctly and securely, review the following guidelines to check other potential USB-related problems:
   • USB ports on the keyboard. USB ports on the keyboard and in the front of some computers might not be powerful enough to support the product. If the USB cable connects to the USB port on the keyboard, try connecting it to another available USB port on the computer.
   • USB cable length. HP supports USB cables less than 5 m (16 feet, 5 inches) long. However, a USB cable that is 5 m (16 feet 5 inches) long must be of high-quality. Otherwise, HP recommends using a USB cable that is less than 2 m (6 feet, 6 inches). Do not use patch cables to increase the length of an existing cable. Use a powered USB hub if you need more length.
   • Alternate USB ports. Connect the USB cable to another port on the computer to make sure that the USB port on the computer is not the problem.
   • Defective USB cable. Replace the USB cable to make sure that the existing cable is not defective.
   • Conflicting USB ports. Disconnect any other USB printers, USB scanners, USB cameras, and any other USB connected peripherals. Start reconnecting these devices one at a time to determine if one of the devices is using too much power. Consider purchasing and installing a powered USB hub if necessary. NOTE: A USB-powered hub is a device that increases the number of available USB ports on a computer and facilitates communication between the USB devices and the computer. A powered USB hub can resolve communication failures between some, but not all, USB chipsets and HP products.
6. After checking the USB connection, print and time a self-test page again.

• If the test page prints in 30 seconds or less , the problem relates to the USB connection. Replace the USB cable or modify the connection to meet the preceding criteria.
• If the test page takes significantly longer than 30 seconds to print, continue to the next solution in this document.

Solution three: Check cartridge compatibility Incompatible cartridges can cause the slow printing problem. To check the cartridge compatibility for your product, go to HP SureSupply .

Hi Did you have any print jobs sent to the printer before replacing the printhead. It seems that the printer is trying to print a job and since the usb cable has been disconnected and reconnected the printer is printing blank pages or misc text.
