HP Pagewide Pro 577dw Troubleshooting
The HP 49.4 C02 Service Error usually occurs when the printer is trying to print a PDF document. This is due to the fact that the font used in the pdf file is too compact and may be affecting the printer's memory. If the PDF file is too large, it is best to print a smaller version first. If that does not solve the problem, you may need to delete the file or clear the printing queue.
