Canon BubbleJet on ECP Port Prints Partial Page

• Microsoft Windows 95

SYMPTOMS

When you print a document to a Canon BubbleJet printer connected to an ECP port, the document may not be printed completely.

This problem is known to occur with the following printers, and may occur with other printers as well:

• Canon BJC-4000
• Canon BJC-70
• Canon BJ-30
• Canon BJ-200

CAUSE

Windows 95 is sending data through the ECP port too fast for the printer to handle.

RESOLUTION

To correct this problem, follow these steps. Note that you must follow these steps in the order they are listed:

1. Configure the port not to be ECP in the computer's CMOS settings. For information about changing CMOS settings, please consult the computer's documentation or manufacturer.

2. Delete the port in Device Manager. To do so, follow these steps:

   a. In Control Panel, double-click the System icon.

   b. On the Device Manager tab, double-click the Ports (COM & LPT)

         branch.
   

   c. Click ECP Print Port (LPTx), and then click Remove.

   d. Click OK.

3. Use the Add New Hardware Wizard to redetect the port. To do so, follow these steps:

   a. In Control Panel, double-click the Add New Hardware icon.

   b. Click Next, click Yes (Recommended), and then click Next.

   c. Follow the instructions on the screen.

   Note that the Add New Hardware Wizard may detect only ECP ports (not standard LPT ports). If this occurs, follow these steps:

   a. Install the ECP port.

   b. In Control Panel, double-click System.

   c. On the Device Manager tab, double-click Ports (COM & LPT), and

         then double-click the ECP port.
